Specifiers Resource Book Concrete Anchoring Concrete Lifting www.ramset.com.au WELCOME TO THE RAMSET™ SPECIFIERS RESOURCE BOOK This concise and systematically presented book contains the information most useful to Architects, Specifiers and Engineers when selecting the concrete anchoring solution that best suits their project. Selection of a concrete anchoring product is made on the basis of the basic type of fixing (male or female, bolt or stud), macro environment, (e.g. coastal or inland), micro environment (particular chemicals) and of course the capacity that best meets the design load case. Where the fixing is simple and does not warrant strength limit state calculations, selection on the basis of load case is made simple and easy with working load limit tables for each concrete anchor. Where more rigorous design and strength limit state calculation is required, the simplified step-by-step method presented in this booklet will allow rapid selection and verification of the appropriate concrete anchor. The Brick and Block anchoring section gives design professionals guidance as to the behaviour of a number of fixings suitable for use in a variety of both solid and hollow pre-manufactured masonry units. The capacity information presented considers the elemental nature of pre-manufactured masonry units and advises designers as to suitable locations within the units accordingly. With the continued growth of Precast Concrete as a construction medium, technical information is presented here, sufficient to enable the selection of appropriate lifting hardware for precast concrete components subject to lifting, handling and erection. In line with current practice, the information is presented in Working Load Limit format, consistant with capacity information presented for cranes, slings, chains, etc. We know that you will find this book both useful and informative.

It is the designers responsibility to ensure compliance with the relevant standards, codes of practice, building regulations, workplace regulations and statutes as applicable. This manual allows the designer to determine load carrying capacities based on actual application and installation conditions. The designer must first select the anchor style/type to suit application and environmental conditions through the use of tables 5.1, 5.2 & 5.3 to identify the specific product features, dimensional properties and environmental characteristics required. Then select an appropriate anchor size to meet the required load case through the use of either the working load information provided or by use of the simplified design process described on the page opposite to arrive at recommendations in line with strength limit state design principles. Ramset™ has developed this Simplified Design Approach to achieve strength limit state design, and to allow for rapid selection of a suitable anchor and through systematic analysis, establish that it will meet the required design criteria under strength limit state principles. The necessary diagrams, tables etc. for each specific product are included in this publication. Ramset™ has also developed a software tool “Ramset Anchor Design” to enable engineers to quickly select suitable anchors for a specific set of design conditions and output the results for project file reference. See section 4 of this publication for further details and an example of how to use the “Ramset Anchor Design” software. 7 3 Simplified Design Approach SIMPLIFIED DESIGN APPROACH 3.1 We have developed this design process to provide accurate anchor performance predictions and allow appropriate design solutions in an efficient and time saving manner. Our experience over many years of anchor design has enabled us to develop this process which enables accurate and quick solutions without the need to work labourously from first principles each time. PRELIMINARY SELECTION Establish the design action effects, N* and V* (Tension and Shear) acting on each anchor being examined using the appropriate load combinations detailed in the AS1170 series of Australian Standards. Refer to charts 5.1, 5.2 and 5.3 in order to select an anchor type that best meets the needs of your application. STRENGTH LIMIT STATE DESIGN STEP 1 Select anchor to be evaluated Refer to table 1a, ‘Indicative combined loading – interaction diagram’ for the anchor type selected, looking up N* and V* to select the anchor size most likely to meet the design requirements. Note that the Interaction Diagram is for a specific concrete compressive strength and does not consider edge distance and anchor spacing effects, hence is a guide only and its use should not replace a complete design process. ACTION Note down the anchor size selected. Having selected an anchor size, check that the design values for edge distance and anchor spacing comply with the absolute minima detailed in table 1b. If your design values do not comply, adjust the design layout. This is an important structural dimension that will be referred to in subsequent tables. Typically, greater effective depths will result in greater tensile capacities. ACTION Note down the anchor effective depth, h. Note also the product part no. referenced. Checkpoint 1 Anchor size selected ? Absolute minima compliance achieved ? Anchor effective depth calculated ? Calculate the anchor effective depth as detailed in step 1c. If the above questions are answered satisfactorily, proceed to step 2. 8 Simplified Design Approach STEP 2 Verify concrete tensile capacity - per anchor Referring to table 2a, determine the reduced characteristic ultimate concrete tensile capacity (ØNuc). This is the basic capacity, uninfluenced by edge distance or anchor spacings and is for the specific concrete compressive strength(s) noted. For designs involving more than one anchor, consideration must be given to the influence of anchor spacing on tensile capacity. Use either of tables 2d or 2e to establish the anchor spacing effect, tension, Xnae or Xnai. ACTION ACTION Note down the value for ØNuc Calculate the concrete compressive strength effect, tension, Xnc by referring to table 2b. This multiplier considers the influence of the actual concrete compressive strength compared to that used in table 2a above. ACTION STEP 3 3 Note down the value for Xnc Note down the value of Xnae or Xnai Checkpoint 2 Design reduced concrete tensile capacity, ØNurc ØNurc = ØNuc * Xnc * Xne * ( Xnae or Xnai ) (kN) If the concrete edge distance is close enough to the anchor being evaluated, that anchors tensile performance may be reduced. Use table 2c, edge distance effect, tension, Xne to determine if the design edge distance influences the anchors tensile capacity. This calculation takes into consideration the influences of concrete compressive strength, edge distance and anchor spacing to arrive at the design reduced concrete tensile capacity. ACTION ACTION Note down the value for Xne Note down the value of ØNurc Verify anchor tensile capacity - per anchor Having calculated the concrete tensile capacity above (ØNurc), consideration must now be given to other failure mechanisms. Calculate the reduced characteristic ultimate steel tensile capacity (ØNus) from table(s) 3a. ACTION Note down the value of ØNus For internally threaded anchoring products that utilise a separate bolt such as the range of Cast-In Ferrules and the DynaSet™ anchor, make use of step 3b to verify the reduced characteristic ultimate bolt steel tensile capacity (ØNtf). Checkpoint 3 Now that we have obtained capacity information for all tensile failure mechanisms, verify which one is controlling the design. Design reduced ultimate tensile capacity, ØNur ØNur = minimum of ØNurc, ØNus, ØNtf Check N* / ØNur ≤ 1, if not satisfied return to step 1 This completes the tensile design process, we now look to verify that adequate shear capacity is available. 9 3 STEP Simplified Design Approach 4 Verify concrete shear capacity - per anchor Referring to table 4a, determine the reduced characteristic ultimate concrete edge shear capacity (ØVuc). This is the basic capacity, uninfluenced by anchor spacings and is for the specific edge distance and concrete compressive strength(s) noted. ACTION Examples n=3 Note down the value for ØVuc V*TOTAL Calculate the concrete compressive strength effect, shear, Xvc by referring to table 4b. This multiplier considers the influence of the actual concrete compressive strength compared to that used in table 4a above. ACTION Note down the value for Xvc n=2 The angle of incidence of the shear load acting towards an edge is considered by the factor Xvd, load direction effect, shear. V*TOTAL Use table 4c to establish its value. ACTION Assume slotted holes to prevent shear take up. Note down the value for Xvd For a row of anchors located close to an edge, the influence of the anchor spacing on the concrete edge shear capacity is considered by the factor Xva, anchor spacing effect, concrete edge shear. Note that this factor deals with a row of anchors parallel to the edge and assumes that all anchors are loaded equally. If designing for a single anchor, Xva = 1.0 ACTION Note down the value for Xva In order to distribute the concrete edge shear evenly to all anchors within a row, calculate the multiple anchors effect, concrete edge shear, Xvn. n=2 V*TOTAL Note: Consider capacity of two anchors in row closest to edge only, ie. anchor load = V*TOTAL/2 to each anchor. ACTION Note down the value for Xvn Checkpoint 4 If designing for a single anchor, Xvn = 1.0 Design reduced concrete shear capacity, ØVurc ØVurc = ØVuc * Xvc * Xvd * Xva * Xvn (kN) This calculation takes into consideration the influences of concrete compressive strength, edge distance and anchor spacing to arrive at the design reduced concrete shear capacity. For a design involving two or more anchors in a row parallel to an edge, this value is the average capacity of each anchor assuming each is loaded equally. ACTION 10 Note down the value of ØVurc Simplified Design Approach STEP 5 3 Verify anchor shear capacity - per anchor Having calculated the concrete shear capacity above (ØVurc), consideration must now be given to other failure mechanisms. Checkpoint Calculate the reduced characteristic ultimate steel shear capacity (ØVus) from table(s) 5a. Design reduced shear capacity, ØVur ACTION 5 Note down the value for ØVus For internally threaded anchoring products that utilise a separate bolt such as the range of Cast-In Ferrules and the DynaSet™ anchor, make use of step 5b to verify the reduced characteristic ultimate bolt steel shear capacity (ØVsf). Now that we have obtained capacity information for all shear failure mechanisms, verify which one is controlling the design. ØVur = minimum of ØVurc, ØVus, ØVsf Check V* / ØVur ≤ 1, if not satisfied return to step 1 This completes the shear design process, we now look to verify that adequate combined capacity is available for load cases having both shear and tensile components. STEP 6 Combined loading and specification For load cases having both tensile and shear components, verify that the relationship represented here is satisfied. Checkpoint 6 Check N*/ØNur + V*/ØVur ≤ 1.2, if not satisfied return to step 1 Specify the product to be used as detailed. 11 3 3.2 Worked Example WORKED EXAMPLE Verify capacity of the anchors detailed below: Given data: Concrete compressive strength f’c 50 MPa Design tensile action effect N*TOTAL 80 kN Design shear action effect V*TOTAL 180 kN Edge distance e 250 mm Anchor spacing a 150 mm Fixture plate + grout thickness t 42 mm No. of anchors in shear n 4 In this case, equal load distribution is considered appropriate hence, Design tensile action effect (per anchor) N* 20 kN Design shear action effect (per anchor) V* 45 kN From the information presented in tables 5.1 – 5.3, it is established that SpaTec™ anchors will be suitable for selection. Having completed the preliminary selection component of the design process, commence the Strength Limit State Design process. 12 A 150 B 150 C D 250 V*TOTAL α = 30° As the design process considers design action effects PER anchor, distribute the total load case to each anchor as is deemed appropriate. Given that each of the ‘interior’ anchors is influenced by two adjacent anchors, verify capacity for anchor ‘B’ in this case. 150 Worked Example STEP 1 Select anchor to be evaluated Refer to table 1a, ‘Indicative combined loading – interaction diagram’ on page 45. Applying both the N* value and V* value to the interaction, it can be seen that the intersection of the two values falls within the M16 “band”. ACTION M16 anchor size selected. The effective depth, h, is calculated by making reference to the ‘Description and Part Numbers’ table on page 44 and calculating effective depth, h = Le - t. Two options are available for the M16 SpaTec™. Given that the fixture thickness value ‘t’ is quite large, select the longer of the two M16 SpaTec™ anchors available. Confirm that absolute minima requirements are met. Hence, h = 150 - 42 = 108 mm From table 1b (page 45) for SpaTec™, it is required that edge distance, e > 170 mm. and that anchor spacing, a > 120 mm. ACTION h = 108 Anchor selected is SA16167 The design values of e = 250 mm and a = 150 mm comply with these minima, hence continue to step 1c. Checkpoint 1 Anchor size selected ? M16 Absolute minima compliance achieved ? Yes Anchor effective depth calculated ? STEP 2 3 h = 108 mm with SA16167 Verify concrete tensile capacity - per anchor Referring to table 2a, consider the value obtained for an M16 anchor at h = 110 mm (closest to our design value of h = 108 mm). ACTION ØNuc = 54.6 kN Verify the concrete compressive strength effect, tension, Xnc value from table 2b. ACTION Xnc = 1.25 As we are considering anchor ‘B’ for this example, use table 2e on page 47 to verify the anchor spacing effect, internal to a row, tension, Xnai value. If we were inspecting anchors ‘A’ or ‘D’ we would use table 2d for anchors at the end of a row. ACTION Xnai = 0.45 Checkpoint 2 Verify the edge distanced effect, tension, Xne value from table 2c. Design reduced concrete tensile capacity, ØNurc ACTION Xne = 1.00 (no effect) ØNurc = ØNuc * Xnc * Xne * Xnai = 54.6 * 1.25 * 1.00 * 0.45 = 30.7 kN ACTION (kN) ØNurc = 30.7 kN 13 3 STEP Worked Example 3 Verify anchor tensile capacity - per anchor From table 3a, verify the reduced characteristic ultimate steel tensile capacity, ØNus. Checkpoint For an M16 SpaTec™, ØNus = 100.5 kN. ACTION 3 ØNur = minimum of ØNurc, ØNus ØNus = 100.5 kN In this case ØNur = 30.7 kN (governed by concrete capacity). Check N* / ØNur ≤ 1, 20 / 30.7 = 0.65 ≤ 1 Tensile design criteria satisfied, proceed to Step 4. STEP 4 Verify concrete shear capacity - per anchor Referring to table 4a, consider the value obtained for an M16 anchor at e = 250 mm. ACTION In order to distribute the shear load evenly to all anchors in the group, the multiple anchors effect, concrete edge shear, Xvn value is retrieved from table 4e. ØVuc = 80.2 kN The ratio of (a / e) for this design case is 150 / 250 = 0.6. Verify the concrete compressive strength effect, tension, Xvc value from table 4b. ACTION ACTION Xvn = 0.69 Xvc = 1.25 Checkpoint Verify the load direction effect, concrete edge shear, Xvd value using table 4c. ACTION Xvd = 1.32 for angle of 30 degrees to normal. Verify the anchor spacing effect, concrete edge shear, Xva value using table 4d. ACTION Design reduced concrete shear capacity, ØVurc ØVurc 5 = ØVuc * Xvc * Xvd * Xva * Xvn = 80.2 * 1.25 * 1.32 * 0.62 * 0.69 = 56.6 kN Xva = 0.62 ACTION STEP 4 ØVurc = 56.6 kN Verify anchor shear capacity - per anchor From table 5a, verify the reduced characteristic ultimate steel shear capacity, ØVus. The shear capacity available from the SpaTec™ anchor is subject to its effective depth, h value. As was noted earlier h = 108 mm for this example, hence, Checkpoint 5 ØVur = minimum of ØVurc, ØVus for an M16 SpaTec™ at h = 108 mm, ØVus = 104.5 kN In this case ØVur = 56.6 kN (governed by concrete capacity). ACTION Check V* ØVus = 104.5 kN / ØVur ≤ 1, 45 / 56.6 = 0.80 ≤ 1 Shear design criteria satisfied, proceed to Step 6. 14 (kN) Worked Example STEP 6 3 Combined loading and specification Checkpoint 6 Check that the combined loading relationship is satisfied: N*/ØNur + V*/ØVur ≤ 1.2, 20 / 30.7 + 45 / 56.6 = 1.44 > 1.2 Combined loading criteria FAILED. Re-consider the design using the adjusted values with anchor spacing, “a” set at 200 mm. ØNuc Xnc Xne Xnai = = = = 54.6 kN 1.25 1.00 0.61 Hence ØNurc = 41.6 kN (at a = 200 mm). Reviewing the design process, examine the critical factors influencing the overall anchor capacity. For tension (governed by concrete failure), ØNuc Xnc Xne Xnai = = = = 54.6 kN 1.25 1.00 0.45 It can be seen from the above values that whilst the concrete compressive strength effect, Xnc improves the design ultimate tensile capacity, the anchor spacing effect, Xnai significantly reduces design ultimate tensile capacity. ØVuc Xvc Xvd Xva Xvn = = = = = 80.2 kN 1.25 1.32 0.66 0.74 (at a = 200 mm, hence a / e = 0.8) Hence ØVurc = 64.6 kN (at a = 200 mm). Now, N*/ØNur + V*/ØVur ≤ 1.2, 20 / 41.6 + 45 / 64.6 = 1.17 < 1.2 Combined loading criteria PASSES. Possible solution: Increase anchor spacing to raise the value of Xnai. For shear (governed by concrete failure), ØVuc Xvc Xvd Xva Xvn = = = = = 80.2 kN 1.25 1.32 0.62 0.69 Specify ™ Ramset SpaTec™ Anchor, M16 (SA16167). Maximum fixed thickness to be 42 mm. To be installed in accordance with Ramset Technical Data Sheet ™ Again, the concrete compressive strength effect, Xvc improves the design ultimate shear capacity. Anchor spacing effect, Xva reduces the design ultimate shear capacity. Possible solution: Increase anchor spacing to raise the value of Xva. Note that increasing the anchor spacing for this design will improve Xnai, Xva and Xvn. 15 4 ANCHOR DESIGN SOFTWARE 4.1 4.1.1 RAMSET™ ANCHOR DESIGN SOFTWARE v1.3 4.1.2 USE OF THE RAMSET™ DESIGN SOFTWARE Ramset™ Anchor Design Software is provided to assist in the choice of a suitable fastener which meets a specific set of design inputs and is intended for use by suitably qualified design professionals.

These are simply details that will help identify the project you are designing and will form part of the printed output that can be stored as part of the project documentation. and to offer a range of anchors which meet the requirement. Additional information prompts with defaults, ensuring it has been considered. Once a selection has been made all inputs, calculated values and installation details are available as output. The Ramset™ Anchor Design Software is ideal for considering complex anchor layouts and grouped anchor configurations. Note that the calculations being performed relate to the single fastener currently at the reference location. The software provides a calculation of the viability of THAT anchor and assumes that all other anchors: ~ are the same type ~ have the same installation conditions, ~ are subject to the same force. On completion of these details, the "Next" button located on the bottom of the screen will move you onto the second input screen. For multiple anchor connections, the design professional must therefore distribute the applied load case(s) to each anchor in the group and evaluate each anchor separately. Material Details This approach allows the designer flexibility in distributing loads to anchors so as to optimise the connection detail without the constraints of a software imposed distribution method. The software will check that the substrate thickness is adequate for allowing anchor capacity to be generated. The Structural Engineer should check the substrates sectional capacity for resisting the applied load. By default the software will select from a wide range of fasteners types that suit the design parameters of the specific anchor. 16 Fig. 1 On the second screen (Fig. 2) enter the Material Details. These refer directly to the substrate properties of the project you are designing. Fields which must be completed are; ~ Fixture and Non Structural Space Thickness This refers to the thickness of the fixture and the non structural gap which is any non structural material (e.g. plaster, grout, packer, foam) in between the substrate and the fixture. ~ Structural Depth and Compressive Strength This refers to the substrate thickness and its compressive strength. Note that the program assumes the substrate is a solid homogeneous material with a particular compressive strength. Therefore it cannot design hollow block fixings, however core-filled blockwork can be analysed using an equivalent compressive strength value. Anchor Design Software Fields which may be completed to help define the anchor selection criteria are: 4 The screen should then be similar to the following. (Note if these fields are left blank then the program will consider all possible anchors in the range that would be suitable for the design conditions you impose.) ~ Fastener Environment These boxes can be "ticked" if there is a particular attribute the anchor must exhibit. e.g. Selecting the "Corrosive" attribute will ensure only galvanised and stainless steel fixings are considered and eliminate zinc plated anchors. ~ Anchor for Consideration You can individually select specific anchor types to be considered in the design, and eliminate any that you do not wish to be evaluated. Fig. 3 You will notice from the above diagram the fastener in the cross hairs is the reference fastener location upon which all calculations are made. You are able to change the fastener to one of the other anchors - details on how to do this can be found by selecting the "Help" button. The "Concrete Compaction Factor" represents the quality of the concrete. For well vibrated and compacted concrete, this value should be set at 1.0. For poorly finished or unsupervised edge concrete, set the value at 1.5. On Completion of all details, the "Next" button moves you onto the final input screen, or alternatively select "Previous" to make any changes to the second input screen. Fig. 2 On completion of the details, the "Next" button will move you onto the third input screen, or alternatively hit "Previous" to make any changes to the first input screen. Layout of Dimensional Considerations. On the third screen (Fig. 3) enter the layout of edges and other fasteners which may affect the design. These are details on the anchor layout, which enable any loss in capacity due to being close to an edge or a neighbouring fastener, of the particular connection you are designing to be taken into account. Select the "Layout" button. Select your anchor group configuration, e.g. for a 2 x 2 anchor layout select the "four" line. Now fill out all the applicable edge distances and spacings. Note that you do not have to enter in all the edges if the anchors are located internally within a slab or panel. Once you are satisfied with the layout, select the "Finish" button. Limit State or Working Load Design The fourth screen (Fig. 4) requires you to enter either the Limit State or Working Load Design Loads - applied load on the single anchor position selected. This refers to the loads applied on the anchor in question, and can either be entered in as a Limit State Load or a Working Load. To design in Limit State, select the "Change to Limit State Design" button. You can then adjust the reduction factors as required. Finally input the applied loads on the anchor you are designing, remembering that this load is applied to the single anchor position only. You will note that the Shear force is split into "Y" and "Z" axis components. Entering a +ve load in the "Y" box will mean it will be directed toward the top of the screen, if you wish to direct the load in the opposite direction simply input the value as a -ve load. Likewise for the "Z" axis. 17 4 Anchor Design Software Fig. 4 On completion, the "Finish" button will commence the computation of all the possible solutions for the parameters you have entered. The possible solutions will be displayed in the "Possible Acceptable Anchors" dialogue box. It is important to note that if the input design parameters were incomplete or no possible solutions could be found, the program will advise as to the reasons why, (e.g. anchors too close to edge). You are then able to adjust the design as detailed, using the design input icons on the summary output screen (Fig. 6). Fig. 6 The icons in the top right hand corner of the screen enable you to navigate through the completed design. The first four from the left are actually the four design input screens you have just completed. The fifth icon (calculator icon) allows you to recalculate for possible solutions in case you make any amendments or would like to select a different anchor. The next icon (printer icon) allows you to print a summary of the design, which will show the project description, anchor layout, design inputs and outputs. More detailed printouts are available if you go to "File" then "Print..." then select the printout you would like. The next icon (disk icon) allows you to save the design for future reference and can be retrieved at a later date. For a copy of our latest Design Software, contact your local specialist Ramset™ Sales Engineer (details on inside front cover) for a demonstration. Fig. 5 You will notice on the above screen that the anchors are listed in order of capacity utilised and also display a relative cost, which is an index cost allowing you to compare the approximate installed cost of the various types of suitable anchors. Select your preferred anchor via the "Select" button and the screen will then show the design output screen. This screen shows you the Design Inputs, parameters which you have entered and computed Design Outputs which includes capacities, governing factors and installation dimensions. If you would like to see the detailed calculations, then select the relevant tabs, i.e. Design, Layout, Cross Section and Installation. 18 5 ENVIRONMENTAL CONSIDERATIONS 5.1 ANCHOR SpaTec HiShear 8.8 Boa Coil TruBolt AnkaScrew DynaBolt DynaSet RediDrive ShureDrive RamPlug EasyDrive ChemSet ChemSet ChemSet ChemSet Nylon Spin 800 Series Hammer 101 Coastal Environment External ✓(SS) ✓(SS) ✓(SS) ✓(SS) ✓(SS) ✓(SS) ✓(SS) ✓(SS) ✓(SS) Coastal Environment Internal ✓(Gal) ✓(Gal) ✓(Gal) ✓(SS) ✓(SS) ✓(Gal) ✓(Gal) ✓(Gal) ✓(Gal) Inland Environment External ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) Inland Environment Internal ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) ✓ ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) ✓(Gal) ✓(SS) ✓(SS) ✓(Gal) ✓(Gal) ✓(Gal) ✓(Gal) ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) Tropical Environment External Tropical Environment Internal ✓(Gal) Alpine Environment External Alpine Environment Internal ✓(Gal) ✓(Gal) ✓(Gal) ✓(Gal) ✓(SS) ✓(SS) ✓(Gal) ✓(Gal) ✓(Gal) ✓(Gal) ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) ✓ ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) ✓(Zn) Industrial Enviro.

becoming more probabilistic in nature and require sound Engineering assessment of both load case information and component capacity data to ensure safety as well as economy. From this value, and dependent on local design requirements, the design professional may then undertake either a strength limit state or working load design assessment of the application at hand, confident that they are working with state of the art capacity information. From a series of controlled performance tests, under test conditions Ultimate Failure Loads are established for a product. Obviously, the value obtained in each test will vary slightly, and after obtaining a sufficient quantity of test samples, the Ultimate Failure Loads are able to be plotted on a chart. Quantity of test results Published capacity data for Ramset™ Fasteners anchoring products are derived from Characteristic Ultimate Capacities. Test values will typically centre about a mean value. Once the mean Failure Load is established, a statistically sound derivation is carried out to establish the Characteristic Ultimate Capacity which allows for the variance in results as well as mean values. The Characteristic Value chosen is that which ensures that a 90% confidence is obtained that 95% of all test results will fall above this value. 24 Xuc x Tested ultimate load x = Mean Ultimate Capacity Xuc = Characteristic Ultimate Capacity 6 Anchoring Technology 6.2 ANCHORING PRINCIPLES 6.2.1 GENERAL 6.2.2 TORQUE SETTING ANCHORS Ramset™ anchors are high quality, precision made fastenings secured with either a torque induced setting action, a displacement induced setting action, a chemical bonding action, or are cast into the plastic concrete. SpaTec™, TruBolt™, and DynaBolt™ anchors are inserted through the hole in the fixture, into a hole drilled into the concrete, and are set by the application of assembly torque to the nut or bolt head. Resistance to tensile loads is provided by mechanisms which depend upon the type of anchor, and its method of setting. Information on the elements that comprise the resistance mechanisms is given separately for each type of anchor. The diameter of the drilled hole is slightly larger than the outer diameter of the anchor. When torque is applied to the bolt head or nut of the anchor, the cone is drawn up into the sleeve to expand its effective diameter. The wedge action of the cone nut in the sleeve increases with increasing torque. The reaction of the concrete against the expanded sleeve of the anchor creates a high friction force between the anchor and the wall of the drilled hole. The body of the concrete contains and restricts the expansion forces. The application of assembly torque produces a preload between the fixture and the concrete. Generally, shear load resistance mechanisms are more uniform amongst anchors, and comprise these elements: ~ the bolt or stud, and in some cases, the steel spacer of the anchor. ~ the ability of the anchor to resist the bending moment induced by the shear force. ~ the compressive strength of the concrete. ~ the shear and tensile strength of the concrete at the surface of the potential concrete failure wedge. When loaded to failure in concrete shear, an anchor located near an edge breaks a triangular wedge away from the concrete. Anchor e Drilled hole Load Concrete Wedge CONCRETE WEDGE FAILURE MODE TORQUE SETTING ACTION SpaTec™, TruBolt™ & DynaBolt™ Anchors If increasing load were to be applied to the fixture, preload would reduce and finally be removed. At this point, the steel cone would begin to be drawn further into the expansion sleeve. When loaded to failure in concrete tension, the failure mode of a correctly installed anchor is characterised by the formation of a concrete cone, the apex of which is located at the effective depth of the anchor. Alternatively, if the tensile capacity of the steel is exceeded, the anchor will break. continued over 25 6 Anchoring Technology 6.2.2 TORQUE SETTING ANCHORS cont. 6.2.3 ROTATION SETTING ANCHORS Effective depth is the effective length, Le of the anchor less the fixture thickness, t. The Boa™ Coil anchor is set by driving the anchor into the hole with a hammer up to the “depth set” mark and then, using a spanner or wrench, rotating the bolt through the coil, thereby setting the anchor. h = Le - t Note that for the purpose of calculating “h”, the fixture thickness “t” should include the thickness of non structural grout, packing, etc. The diameter of the drilled hole is a similar size to that of the anchor. Resistance to tensile load is provided by the two (2) components which make up the Boa™ Coil anchor, the “bolt” and the “coil”. t h The reaction of the concrete against the expanded anchor creates a high friction force and an undercut forms between the anchor and the hole wall. The body of the concrete contains and restricts the expansion forces. The action of tightening the anchor bolt against the fixture produces a preload between the fixture and the concrete. Le As the applied tensile load increases, a commensurate decrease in preload occurs, until at some point after all preload has been removed, first slip occurs. Concrete is locally crushed around the coil as it beds in further, accompanied by an increase in load capacity. Applied tensile loads are resisted by these elements: ~ the anchor bolt or stud. ~ the wedge action of the steel cone in the sleeve. ~ friction between the expanded sleeve and the drilled hole. ~ shear and tension at the surface of the potential concrete cone. Applied tensile load Anchor CONCRETE CONE FAILURE MODE 26 When failure occurs in the concrete the mode of failure is a broaching effect whereby load is still being held until the applied load is equivalent to the shear and tensile capacity of the concrete, at this point a cone of failure occurs. There is little or no damage done to the anchor bolt, but the Boa™ Coil is destroyed, and must be replaced if the anchor bolt is to be re-used. Anchoring Technology 6 6.2.4 DISPLACEMENT SETTING ANCHORS 6.2.5 CHEMICAL ANCHORS DynaSet™ anchors are inserted into a drilled hole, and set by the displacement of the expander plug. ChemSet™ Maxima™ Spin Capsules, ChemSet™ Hammer Capsules, ChemSet™ Injection Systems anchors are set in a drilled hole by the hardening of the chemical mortar. Setting tool CHEMICAL ANCHORING DISPLACEMENT SETTING DYNASET™ ANCHORS The diameter of the drilled hole is slightly larger than the outer diameter of the anchor. When the expander plug is fully driven home (displaced), it expands the lower portion of the anchor body, to increase its effective diameter. Because the anchor is expanded by a series of blows to a setting punch, a certain amount of shock loading is imparted to the concrete immediately adjacent. The reaction of the concrete against the expanded body of the anchor creates a high friction force between the anchor and the wall of the drilled hole. The body of the concrete contains and restricts the expansion forces. A bolt is subsequently screwed into the anchor. The mode of failure in concrete tension is characterised by the formation of a shear cone, the apex of which is located at the effective depth of the anchor. The mortar penetrates the pores and irregularities of the base material and forms a key around the threads of the stud. The cured mortar becomes a hard, strong material that transfers load to the base material via mechanical and adhesive bonds with the surface of the drilled hole. When tested to failure, a shallow concrete cone may form at the top of the anchor. This cone does not necessarily contribute to the tensile strength of the anchor, but simply registers the depth at which the concrete cone strength happens to equate to the cumulative bond strength of the adhesive to the sides of the hole. For a given concrete strength, the stronger the adhesive bond, the deeper the cone. Applied tensile loads are resisted by: ~ the stud. ~ bond between the stud and the mortar shear in the mortar bond between the mortar and the concrete. ~ shear and tension in the concrete. Applied tensile loads are resisted by the following elements: ~ the bolt. ~ the steel annulus of the anchor. ~ friction between the expanded anchor and the drilled hole. ~ shear and tension at the surface of the potential concrete cone. Anchor Applied tensile load Concrete cone Adhesive covered stud CONCRETE BOND FAILURE MODE 27 6 Anchoring Technology 6.2.6 CAST-IN ANCHORS Prior to pouring the concrete, Ramset™ Ferrules are placed in the form and typically fixed to it or to the reinforcement mesh. They are retained in the hardened concrete by either the enlargement on the base of the anchor, or by a bar located in the cross-hole. The mode of failure in concrete tension, is characterised by the formation of a concrete cone, the apex of which is located at the effective depth of the anchor. Applied tensile loads are resisted by: ELEPHANTS' FEET, ROUND & TCM FERRULES ~ the bolt screwed into the insert. ~ the steel annulus of the insert. ~ steel capacity at the reduced section (cross-hole). ~ shear strength in the base enlargement, or the cross-bar. ~ shear and tension at the surface of the potential concrete cone. 6.3 BASE MATERIALS 6.3.1 SUITABILITY Ramset™ anchors can be used in plain or in reinforced concrete. It is recommended that the cutting of reinforcement be avoided. The specified characteristic compressive strength "f’c" will not automatically be appropriate at the particular location of the anchor. The designer should assess the strength of the concrete at the location of the anchor making due allowance for degree of compaction, age of the concrete, and curing conditions. Particular care should be taken in assessing strength near edges and corners, because of the increased risk of poor compaction and curing. Where the anchor is to be placed effectively in the cover zone of closely spaced reinforcement, the designer should take account of the risk of separation under load of the cover concrete from the reinforcement. Concrete strength "f’c" determined by standard cylinders, is used directly in the equations. Where strength is expressed in concrete cubes, a conversion is given in the following table: Cube Strength β (N/mm2) 20 30 40 50 60 Cylinder Strength f’c (MPa) 15 24 33 42 51 The design engineer is responsible for the overall design and dimensioning of the structural element to resist the service loads applied to it by the anchor. 28 Where structural base materials are covered with a non-structural material such as plaster or render, anchors should be embedded to the design depth in the structural base material. Allowance must be made for the thickness of the non-structural material when considering the application of shear loads, and in determining the moment arm of applied bending moments. In hollow block masonry, where the cores are filled with concrete grout, Ramset™ anchors may be designed and specified similarly as in concrete, provided the designer assesses the effective strength of the masonry including the joints. However, it is not advisable to use certain heavy duty anchors in unfilled hollow masonry units (either bricks or blocks). These heavy duty anchors include all SpaTec™, TruBolt™ and ChemSet™ capsule anchors, and DynaBolt™, Boa™ Coil anchor, DynaSet™, and Chemical Injection anchors greater than M12 in diameter. In any case the designer should assess the effective strength of the masonry including the joints, and determine how the loading is to be transferred to the masonry structure. Load tests should be conducted on site to assist in assessing masonry strength. Ramset™ heavy and medium duty anchors are not recommended for low strength base materials such as autoclaved aerated concrete, except for ChemSet™ Injection System studs up to M12. 6 Anchoring Technology 6.3.2 ABSOLUTE MINIMUM DIMENSIONS Spacings, edge distances, and concrete thicknesses are limited to absolute minima, in order to avoid risks of splitting or spalling of the concrete during the setting of Ramset™ torque and displacement setting expansion anchors. Absolute minima for stress-free anchorages such as chemical and cast-in anchors are defined on the basis of notional limits, which take account of the practicalities of anchor placement. The concrete thickness minima given below, does not include concrete cover requirements, and are not a guide to the structural dimensions of the element. It is the responsibility of the design engineer to proportion and reinforce the structural element to carry the loads and moments applied to it by the anchorage, and to ensure that the appropriate cover is obtained. Absolute minimum spacing "am" and absolute minimum edge distance "em", define prohibited zones where no anchor should be placed. The prohibited spacing zone around an anchor has a radius equal to the absolute minimum spacing. The prohibited zone at an edge has a width equal to the absolute minimum edge distance. In order to avoid ‘breakthrough’ during drilling of the hole into which anchors will be installed, maintain a cover value to the base of the hole equal to 2x the drilled hole diameter, dh. ie. for a hole of 20 mm diameter allow 40 mm cover to the rear face of the substrate component. Free zone am Prohibited zone Where an anchor is installed at the absolute minimum edge distance "em", concrete thickness is at a maximum of 2 * h. (Effective depth "h", is measured from the concrete surface to the end of the anchor expansion sleeve unless otherwise stated.) Prohibited zone em In certain circumstances, it may be possible to install anchors in thinner concrete elements. If cover to the anchor is not required, and a degree of spalling can be tolerated between the end of the expansion sleeve and the far surface of the concrete, embedment close to the far surface may be feasible. More information on the conditions for reduced concrete thickness may be obtained from Ramset™ Engineers. Edge distance "e" Concrete Edge PROHIBITED ZONES FOR SPACINGS AND EDGES Where an expansion anchor is placed at a corner, there is less resistance to splitting, because of the smaller bulk of concrete around the anchor. In order to protect the concrete, the minimum distance from one of the edges is increased to twice the absolute minimum.

Explanations of this approach are found in the design standards for structural steel and concrete. When designing for strength the anchor is to comply with the following: L (applied load) ≤ Ra (working load limit capacity) Working load limits are derived from characteristic ultimate capacities and factor of safety: Ra = Ru / Fs ØRu ≥ S* Factors of safety are related to the mode of failure, and material type, and the following are considered appropriate for structural anchoring designs: where: Ø = capacity reduction factor fss = factor of safety for steel in tension and bending = 2.2 Ru = characteristic ultimate load carrying capacity S* = design action effect fsv = factor of safety for steel in shear = 2.5 fsc = factor of safety for concrete = 3.0 ØRu = design strength Design action effects are the forces, moments, and other effects, produced by agents such as loads, which act on a structure. They include axial forces (N*), shear forces (V*), and moments (M*), which are established from the appropriate combinations of factored loads as detailed in the AS1170 “Minimum Design Load on Structures” series of Australian Standards. Capacity reduction factors are given below, these typically comply with those detailed in AS4100 - “Steel Structures” and AS3600 - “Concrete Structures”. The following capacity reduction factors are considered typical: Øc = = capacity reduction factor, concrete tension 0.6 Øq = = capacity reduction factor, concrete shear 0.6 Øn = = capacity reduction factor, steel tension 0.8 Øv = = capacity reduction factor, steel shear 0.8 Øm = = capacity reduction factor, steel bending 0.8 Whilst these values are used throughout this document, other values may be used by making the adjustment for Ø as required. 30 6 Anchoring Technology 6.5 TENSION 6.5.1 STEEL TENSION 6.5.2 CONCRETE CONE The characteristic ultimate tensile capacity for the steel of an anchor is obtained from: Characteristic ultimate tensile capacities for mechanical anchors vary in a predictable manner with the relationship between: - hole diameter (dh) - effective depth (h), and - concrete compressive strength (f’c) Nus = As fu where: within a limited range of effective depths, h. Nus = characteristic ultimate steel tensile capacity (N) This is typically expressed by a formula such as: = tensile area = stress area for threaded sections (mm2) (mm2) fu = characteristic ultimate tensile strength (MPa) fy = characteristic yield strength (MPa) As The tensile working load limit (permissible stress method) for the steel of a Ramset™ anchor is obtained from: Nas = Nus / 2.2 Nuc = factor * dbfactor * h1.5 * √f’c Anchors may have constraints that apply to the effective depth of the anchor or the maximum or minimum concrete strength applicable. Effective anchor depth is taken from the surface of the structural concrete to the point where the concrete cone is generated. In establishing the effective depth for anchors, the designer should allow for any gap expected to exist between the fixture and the concrete prior to clamping down. air gap h h h EFFECTIVE DEPTH FOR ANCHORS The appropriate concrete compressive strength "f’c" is the actual strength at the location of the anchor, making due allowance for site conditions, such as degree of compaction, age of concrete, and curing method. Concrete tensile working load limits (permissible stress method) for anchors are obtained from: Nac = Nuc / 3.0 31 6 Anchoring Technology 6.5.3 PULL-THROUGH 6.5.4 CONCRETE BOND This mode of failure occurs in expansion anchors under tensile loading, where the applied load exceeds the frictional resistance between either the cone and the expansion sleeve, or the sleeve and the sides of the drilled hole in the concrete. Failures of this type are often associated with anchors that are improperly set, or used in larger diameter holes drilled into the concrete with over-sized drill bits. Chemical Anchors The load carrying capacities of anchors with thick-walled expansion sleeves such as SpaTec™ and properly-set DynaSet™ anchors, are not sensitive to this mode of failure. The recommended limits on concrete strength "f’c" in the determination of concrete cone strength for DynaBolt™ and TruBolt™ anchors, act as a precaution against this mode of failure. Characteristic ultimate tensile load carrying capacities for concrete bond failure in the compression zone varies with hole depth, effective depth and concrete strength in a similar manner to concrete cone failure in mechanical anchors. Effective anchor depth "h" is taken from the start of the adhesive, (usually the surface of the concrete) to the bottom of the stud. For chemical capsule anchors, it is not usual to deviate from the depths given in the Section Properties and Data. Whilst it is essential to provide sufficient resin to fill the space between the stud and the concrete, the installer must avoid excessive overspill. Hole depths for capsule anchors may be increased in increments related to the volume of capsules available. It is recommended to seek advice from Ramset™ Technical Staff before deviating from the recommended hole depths or hole diameters. h EFFECTIVE DEPTH FOR CHEMICAL ANCHORS The appropriate concrete strength "f’c" to be used in these equations, is the actual strength at the location of the anchor, making due allowance for site conditions, such as degree of compaction, age of concrete, and curing method. Concrete tensile working load limits (permissible stress method) for Ramset™ chemical anchors are obtained from: Nac = Nuc / 3.0 32 Anchoring Technology 6 6.5.5 CRITICAL SPACING In a group of mechanical anchors loaded in tension, the spacing at which the cone shaped zones of concrete failure just begin to overlap at the surface of the concrete, is termed the critical spacing, ac. ac For anchors influenced by the cones of two other anchors, as a result for example, of location internal to a row: Xna = a / ac ≤ 1 Unequal distances ("a1" and "a2", both < ac) from two adjacent anchors, are averaged for an anchor internal to a row: a Xna = 0.5 (a1 + a2) / ac Anchors If the anchors are at the ends of a row, each influenced by the cone of only one other anchor: Cone of Failure For chemical anchors the critical spacing is determined by interference between the cylindrically shaped zones of stress surrounding the anchors. ac a Bond cylinders Xna = 0.5 (1 + a/ac) ≤ 1 The cone of anchor A is influenced by the cones of anchors B and C, but not additionally by the cone of anchor D. "Xna" is the appropriate reduction factor as a conservative solution. Anchors Critical spacing defines a critical zone around a given anchor, for the placement of further anchors. The critical spacing zone has a radius equal to the critical spacing. The concrete tensile strengths of anchors falling within the critical zone are reduced. For clarity, the figure includes the prohibited zone as well as the critical zone. At the critical spacing, the capacity of one anchor is on the point of being reduced by the zone of influence of the other anchor. Ramset™ anchors placed at or greater than critical spacings are able to develop their full tensile loads, as limited by concrete cone or concrete bond capacity. Anchors at spacings less than critical are subject to reduction in allowable concrete tensile loads. Both ultimate and working loads on anchors spaced between the critical and the absolute minimum, are subject to a reduction factor "Xna", the value of which depends upon the position of the anchor within the row: Nucr = Xna * Nuc A B C D ANCHOR GROUP INTERACTION CRITICAL REDUCTION PROHIBITED a ≥ ac ac > a > am a < am No influence.

Cast-In and Expansion Anchors The critical edge distance (ec) for expansion and cast-in anchors is taken as one and a half times effective depth: ec Chemical Anchors For chemical anchors the critical edge distance is determined by interference between the edge and the cylindrically shaped zones of stress surrounding the anchors. ec = 4 * db = 1.5 * h ec ec Anchor Bond cylinder Anchor Cone of Failure e INTERFERENCE OF EDGE WITH BOND CYLINDER INTERFERENCE OF EDGE WITH CONCRETE CONES If the edge lies between the critical and the absolute minimum distance from the anchor, the concrete tensile load reduction co-efficient "Xe", is obtained from the following formula: Rotation Set Anchors Xe The critical edge distance for Boa™ Coil anchor is taken as: where: ec Xe = 6 * db = 0.3 + 0.7 * e / ec ≤ 1 = edge reduction factor tension Critical edge distances define critical zones for the placement of anchors with respect to an edge. The critical edge zone has a width equal to the critical edge distance. The concrete tensile strengths of anchors falling within the critical zone are reduced. For clarity, the figure includes the prohibited zone as well as the critical zone. em Concrete Edge ec Free zone Critical zone Prohibited zone CRITICAL EDGE ZONE 34 Anchoring Technology SHEAR 5.6.1 ANCHOR STEEL SHEAR For an anchor not located close to another anchor nor to a free concrete edge, the ultimate shear load will be determined by the steel shear strength of the anchor, provided the effective depth of the anchor is compliant with the following: SpaTec™ h The designer should also take into account any conditions that may cause bending moments and unbalanced forces to be applied simultaneously. Any tendency of the fixture to lift away from the surface under load will generate moments and tension forces. The characteristic ultimate shear capacity (Vus) for the steel of an anchor is obtained from: ≥ 4 * dh Vus = 0.62 * As * fu (N) 4 * dh Minimum for bolt shear dh 6.6.2 CONCRETE EDGE SHEAR 1.25 * db Minimum for bolt and spacer shear Where load is directed either towards or parallel to an edge, and the anchor is located in the proximity of the edge, failure may occur in the concrete. MINIMUM INSERTION FOR BOLT SHEAR ™ For SpaTec it is required that the bottom end of the spacer is inserted at least one and a quarter times hole diameter (1.25 * dh) in order for the shear strength of the spacer to be allowed as contributing to the shear strength of the anchor. Anchor e Drilled hole Load Concrete Wedge Boa™ Coil For full bolt shear, h ≥ 6 * db CONCRETE WEDGE FAILURE MODE A reduced shear capacity is applicable down to a minimum value of 3 * db. 3 * db Minimum for bolt shear dh 6.6 6 MINIMUM INSERTION FOR BOLT SHEAR TruBolt™ h ≥ 4 * dh DynaBolt™ h ≥ 3.5 * dh DynaSet™ anchors are not normally embedded to four times the diameter of the drilled hole, and their characteristic shear capacities relate to the bending strength of the anchor or shear of the inserted bolt. 35 6 Anchoring Technology 6.6.3 SPACING UNDER CONCRETE SHEAR At a spacing of at least 2.5 times edge distance, there is no interference between adjacent failure wedges. Where anchor spacing is less than 2.5 times edge distance, the shear load capacities in the concrete are subject to a reduction factor "Xva". Failure wedge a a Two anchors installed on a line normal to the edge, and loaded in shear towards the edge, are treated as a special case. Where the anchors are loaded simultaneously by the same fixture, the ultimate or the concrete edge shear capacity for each anchor will be influenced by the other anchor. Where the spacing "a" between anchors A and B is less than or equal to "eB" the edge distance of anchor B, the ultimate edge shear for anchor A is equal to anchor B, despite the longer edge distance of anchor A: e Concrete edge Shear force A INTERFERENCE BETWEEN SHEAR WEDGES a Xva = 0.5 ( 1 + a / (2.5 * e)) ≤ 1 The direction of the shear load towards an edge will influence the concrete edge shear capacity. This is accounted for with the factor Xvd. B Concrete edge Failure wedge eB ANCHORS IN LINE TOWARDS AN EDGE For an anchor located at a corner and where the second edge is parallel to the applied shear, interference by the second edge upon the shear wedge is taken into account by the following reduction factor: α V* Xvs = 0.30 + 0.56 * e1 / e2 ≤ 1 When a row of anchors is subject to a shear load acting towards an edge, the distribution of each anchors capacity in the anchor group is derived by using the factor Xvn. e1 Shear Force e2 Failure wedge V*A V*B V*C Concrete edges n=3 V*TOTAL V*A = V*B = V*C ØVur ≥ V*A, V*B, V*C 36 ANCHOR AT A CORNER Anchoring Technology 6.7 6 BENDING The designer's calculation of the design bending moment (M*) should include an allowance in the moment arm of one hole diameter inwards from the face of the concrete: In the case of working load limit design, applied moments (M) are calculated as follows: M = V * ( dh + g + t / 2) V = applied shear force M* = V* * ( dh + g + t / 2) (N) where: V* = shear design action effect (N) Characteristic ultimate bending capacities (Mu), are obtained from the following formula: g = gap between fixture and concrete surface (mm) M u = fy * Z t = fixture thickness (mm) where: Non-structural One hole diameter material or gap fy = characteristic yield strength (MPa) Z = section modulus of the anchor (mm3) Fixture and for working load limit bending moment (Ma): Ma = Mu / fss = Mu / 2.2 Applied load Moment arm DESIGN BENDING MOMENT Anchor moments need only be considered if there is a non structural material or gap between the fixture and substrate that results in application of a moment to the anchor itself. 37 6 6.8 Anchoring Technology COMBINED LOADING 6.8.1 TENSION AND BENDING 6.8.3 TENSION AND SHEAR Where an anchor is subjected to combined tension and bending, ultimate tensile capacity for the steel is determined as follows: Design for combined tension and shear, requires firstly the determination of anchor capacities. Strength limit state design capacities are taken as: ØNur = ØcNurc ≤ ØnNus Nusr = Nus * (1 - (M* / ØmMu)) ØVur = ØqVur ≤ ØvVus where: where: Øm = capacity reduction factor, steel bending, recommended as 0.8 Ø = capacity reduction factor ØNur = design reduced ultimate tensile capacity Applied tension ØVur = design reduced ultimate shear capacity Øc = capacity reduction factor concrete tension Øq = edge capacity reduction factor concrete shear, recommended as 0.6 Øn = capacity reduction factor, steel tension, recommended as 0.8 Factored working load limit steel tensile capacities, to allow for the effects of bending moments are given by: Øv = capacity reduction factor, steel shear, recommended as 0.8 Nasr = Nas * (1 - M / Ma) Working load capacities are determined as follows: Applied moment Moment arm COMBINED TENSION, SHEAR AND BENDING Na = Nar ≤ Nsr where: Va = Var ≤ Vas Nasr = factored working load limit steel tensile capacity (N) where: Na = working load limit tensile capacity 6.8.2 SHEAR AND BENDING There is no reduction in shear capacity in the case of combined bending and shear. Shear capacity and bending capacity are checked independently.

Under the relevant loading condition, as a general principle, all load reduction factors applicable to an individual anchor in the group should be multiplied together to account for the combined effects on the anchor of multiple loads, group layout, and base material geometry. In the application of loads, due allowance should be made for eccentricities in the lines of action of loads relative to the centroid of the group, and for any other conditions likely to cause a magnification of load to an anchor, i.e. prying forces. In a group loaded in shear there is a risk of uneven loading, particularly where more than two anchors are arranged one behind the other in the direction of the load. The designer should assess and make appropriate allowance for the ability of the fixture to distribute the load to anchors in the group. The simplified strength limit state design process detailed in this document is intended to cover a wide range of applications. It is suitable for verifying capacity of single anchors or groups of anchors, however it must be remembered that the capacity data given is PER ANCHOR and load cases must be distributed to all anchors in a group and each anchor verified as being suitable. For a row of anchors subject to a shear force component towards an edge, the design tables assume that the design load case is evenly distributed to all anchors in the group and calculates the averaged shear capacity for each anchor. V*A = V*B = V*C V*A V*B V*C V*TOTAL n=3 ØVur = per anchor capacity It is unable to verify capacity for anchors in the following configurations: • Location at a corner with shear load component towards the edge(s).

V*A + V*B + V*C = V*TOTAL V*TOTAL 39 6 6.10 Anchoring Technology ASSEMBLY TORQUE AND PRELOAD The application of assembly torque to a well designed anchor, results in the generation of a preload or clamping force between the fixture and the concrete. Because the fixture supports the concrete and suppresses cone failure, preload may exceed concrete cone failure load. The concrete experiences an elastic compression beneath the fixture. Under external loading of the fixture, the surfaces of the joint will not separate until the applied load exceeds the preload. Although the magnitude of the preload influences the deformation of the fixing under load, it does not in general, affect the ultimate static load capacity of the fixing. Preload or clamping load Clamped material Applied load Boa™ Coil anchors and stud anchors such as TruBolt™ anchors and chemical anchors also have the capability to clamp the fixture to the concrete. Torque controlled expansion anchors without an adequate pulldown capability, suffer from loss of preload to the spacer or sleeve, whenever there is a gap between the mating surfaces. This results in a reduction in the preload available for compression of the concrete. Such anchors may perform under cyclic loads as if there were an inadequate preload, even though the specified assembly torque may have been carefully applied. In some instances it is possible for the fixture to be loose against the concrete surface from the time of initial assembly of the fixing. Initial preload (PLi) which is developed immediately after the application of assembly torque, is calculated for Ramset™ anchors as: PLi = α * Pr PRELOADING OF FIXTURE TO CONCRETE Heavy and medium duty sleeve anchors with a fully functioning pull-down mechanism such as Ramset™ SpaTec™ and DynaBolt™ anchors, ensure that loss of preload to the spacer or sleeve is negligible, even where a substantial gap may have existed between the concrete and the fixture, due to unevennesses in the mating surfaces. After the expansion sleeve has enlarged to grip the sides of the hole, the pull-down mechanism allows the gap to be closed and the fixture to be clamped against the concrete. where: α = proportion of proof load as initial preload 65% for mechanical anchors 25% for chemical anchors Pr = bolt or anchor proof load = A s * fy Assembly torques required (Tr) to develop initial preloads are given by the following formula: Tr = µT * db * PLi where: µT = torque co-efficient of sliding friction 0.14 for SpaTec™ anchors 0.32 for cold-formed anchors and stainless steel anchors 0.37 for machined anchors SpaTec™ and DynaBolt™ Anchors PULL DOWN MECHANISMS 40 (kN) 6 Anchoring Technology 6.11 LONG TERM PRELOAD DEGRADATION In considering the long term performance in concrete of expansion and cast-in anchors under cyclic loading, account must be taken of concrete creep which causes a degradation of preload over time. Immediately after the application of assembly torque and the establishment of initial preload, there is a rapid initial reduction in preload, followed by a continued gradual reduction over time, towards a long term limiting value of "PL", at "λ" % of initial preload. As a guide, "λ" may be taken as typically 70% for SpaTec™ anchors, and as 40% for DynaBolt™ and TruBolt™ anchors. 1.0 PL/PLi λ 0 3 6 Time (Months) 9 12 PRELOAD DEGRADATION In a particular application, the proportion of preload permanently retained will depend upon concrete strength, concrete quality including curing, level and direction of concrete stress, applied load level, timing of applied loads, and the value of the total spring rate for the anchor/fixture/base material system. 41 6 6.12 Anchoring Technology SLIP LOAD AND CYCLIC LOADING Provided the applied load is less than the remaining preload, slip virtually does not occur, and the fixing experiences the applied load as a reduction in elastic compression of the concrete. When the applied load exceeds the preload, the clamped material can separate from the concrete and slippage of the joint can commence. If the design requirement is for negligible slip (say 0.1mm), the assembly torque should be both carefully specified and applied. It is recommended that anchor capacity be limited to a percentage of the expected preload after allowing for long term degradation. Ultimate load Applied load The Boa™ Coil anchor performs more like a slight undercut anchor where the first slip measured at 0.1mm is close to the ultimate load of the anchor in concrete. The Boa™ Coil anchors ability to sustain cyclic loads depends primarily upon the interaction of the Boa™ Coil and the concrete sides of the hole. It is this unique interaction that enables the Boa™ Coil anchor to achieve high first slip loads. To ensure long life of the fastener under cyclic loading the designer should ensure (as for slip loads), that the applied load does not exceed 65% of the first slip load, called the reduced characteristic ultimate slip load. When the applied load is less than the reduced characteristic ultimate slip load the Boa™ Coil anchor has the ability to withstand an infinite number of repetitions of the applied load. Long term preload = slip load Ultimate load Long term preload = slip load 65% of slip load Applied load 65% of slip load Displacement SLIP LOAD AND PRELOAD The ability of an anchor to sustain cyclic loads depends (as for slip loads) primarily upon the relationship between the applied load and the effective preload in the anchor. Where the applied load is less than both the preload and the static working load, the fastening has the ability to withstand an infinite number of repetitions of the applied load. The cyclic loading is experienced as changes in pressure at the interface of the fixture and the concrete, and the stress range in the anchor should never approach the endurance limit. To ensure long life of the fastening under cyclic loading, the designer should ensure (as for slip loads), that the applied load is less than "h" % of the expected long term preload after allowing for degradation. 42 Displacement SLIP LOAD Anchoring Technology 6.13 CORROSION During their service life, fasteners may be subjected to a range of corrosive agents and environments. Atmospheric environments may include the benign, such as indoors in dry conditions. The less benign outdoor areas are exposed to rain and/or humidity. The chloride bearing atmospheres under the influence of sea winds are more corrosive. The polluted atmosphere in some industrial areas, and the marine environment over the sea, at the shore, or within the splash zone, may be highly aggressive. Fastenings may be required to be placed under fresh water, salt water, or in contact with a whole range of potentially corrosive liquids. Ramset™ anchors are supplied with a range of corrosion resistances suitable for various applications. The term “galvanised” in this document refers to hot dip galvanising according to the Australian Standards listed in the table below. Note that other publications may use the term “galvanised” when referring to zinc electroplated anchors, which provides inferior corrosion protection. To ensure adequate corrosion protection, verify that the plating thickness complies with the thickness value required by the relevant Australian Standard. AS1214 - 1983 requires a minimum of 42 micron thickness for “hot dip galvanised” threaded items. ENVIRONMENT There is a large number of specialist texts on the subject of corrosion, to which the reader is referred. The stainless steel specification for Ramset™ anchors has a high molybdenum content, which gives superior resistance against chlorides and common industrial pollutants. Stainless steel anchors should be insulated from the zinc coating, when securing galvanised steelwork, because of the possibility of galvanic corrosion. Care must be taken to ensure selected fasteners meet the appropriate standards and are also correctly described. For example, “mechanically galvanised” is a misnomer for “mechanically plated”, which may not provide the same corrosion protection as “hot dip galvanising”.

Designers have traditionally adopted this limiting temperature for the retention of structural integrity. Expansion and cast-in anchors manufactured in steel, are subject to the same limit, except that conditions are generally more favourable to the retention of structural strength for these anchors, than other components of an unprotected structure. For example, in circumstances where heat can be expected to vent through the roof sheeting, there is little risk of the fixings at the supports of steel beams, reaching the same temperature as the most critical part of the main steel structural elements. Generally, fixings reach significantly lower temperatures than the main structural elements. Fire induced deformations of wall panels, and the behaviour of the structural frame under fire, should be carefully considered in the design. Spread of the fire to adjoining properties will be prevented, as long as the panels remain fixed to the structural frame. The connection between a heavy structural steel frame and the wall panels should be via deformable ties. The limiting operational temperature for chemical anchors is 80°C. When used for anchoring reinforcing steel, chemical systems are provided with concrete cover, and may be designed to provide the desired fire rating, by limiting the temperature rise at the anchor points. Where protection is required for the steel structure, special fireproofing material is specified. The same protection should be extended to any exposed fixings to the concrete structure. Part of an anchor is always embedded in and insulated by the concrete, which increases the time for the heat to flow to the anchoring element of the anchor, and because of the heat sink of the concrete mass which takes heat from the anchor, there is an increase in the time for its temperature to rise. 43 MECHANICAL ANCHORING OVERVIEW Ramset™ have been offering mechanical anchors in the Australian market place for over 40 years. During this time Ramset™ brand names have entered into common language on building sites all over Australia. Names like DynaBolt™ and TruBolt™ have become recognised as the best sleeve anchors and stud anchors alike. But only Ramset™ supplies the original, proven products like DynaBolt™ sleeve anchors, TruBolt™ stud anchors, SpaTec™ heavy duty anchors and DynaSet™ female anchors. These tried and tested Ramset™ brand names represent Quality, Reliability and Performance. The Ramset™ ISO9001 accreditation assures it. Not only does Ramset™ offer reliable, quality product. Ramset™ understands masonry anchoring technology and offers published information, such as this book, to guide correct product selection and safe installation. Extensive research, development and testing are invested in Ramset™ products so that designers can be secure in the knowledge that they have access to the real performance and capabilities of the anchors. It is performance that defines an anchor’s capabilities. An anchor’s performance cannot be deduced from its description. For example not all sleeve anchors perform like DynaBolt™ sleeve anchors and not all stud anchors perform like TruBolt™ stud anchors. Product design, manufacturing tolerances and manufacturing quality control have a major affect on anchor performance. The only way to determine an anchor’s actual performance is to measure it at all of its design and tolerance limits. The performance of Ramset™ Anchors are determined by extensive and rigorous testing to enable us to provide information on how our products will perform over a wide range of conditions and advise as to their limitations. The correct anchor for a particular load case can only be selected by referring to reliable design information issued by the supplier for their anchors. Performance and design information from one supplier does not apply to anchors from other suppliers, even if they appear to be the same or have the same generic description. The following section introduces the designer and/or engineer to the Ramset™ mechanical anchoring range and provides performance information to allow selection of the right anchor for the job. 44 Mechanical Anchoring SpaTec™ 7.1 7 SpaTec™ Safety Anchors GENERAL INFORMATION PERFORMANCE RELATED MATERIAL INSTALLATION RELATED Product The SpaTec™ Anchor is a heavy duty, torque setting expansion anchor.

Benefits, Advantages and Features High load capacity: ~ Expansion coil locks into concrete to give cast-in type performance. High clamping load: ~ Rotation setting action pulls down. Principal Applications Resistant to cyclic loading: ~ Pull-down action. Fast installation: ~ Through fixing eliminates marking out and repositioning of fixtures. Easy and fast to remove: ~ Expansion coil stays in hole leaving no protruding metal parts to grind off. ~ Installing handrails and balustrades. ~ Anchoring braces and precast panels. ~ Machinery hold down. ~ Formwork support. ~ Safety barriers. Installation 1. Using the fixture as a template, drill the correct diameter and depth hole. Clean hole with a brush and remove debris with vacuum or hand pump. 2. Insert the assembled Boa™ Coil anchor. (The coil tab points up the anchor.) Tap anchor down to depth set mark and stop. 3. Wind the anchor down until the washer is firmly held to the fixture and stop. (For the number of turns required to set anchor refer to details on installation and performance.) 4. Ensure washer is tight and snug fit. 5. The Boa™ Coil anchor is ready to take load. (The bolt can be removed leaving the coil in the hole. To re-insert, follow steps 3 and 4.) 61 9 Mechanical Anchoring Boa™ Coil Installation and Working Load Limit performance details Anchor size, db (mm) 10 13 16 19 Installation details Minimum dimensions* Drilled hole Fixture hole Anchor Edge Anchor Substrate Turns to distance, e spacing, a thickness, b Shear, V diameter, dh diameter, df effective c c m a (mm) (mm) depth, h (mm) set anchor (mm) (mm) (mm) 30 45 4.5 10 12 50 5 60 120 75 7.4 75 113 8.9 40 60 8.2 13 14 75 5 80 160 113 15.4 110 165 16.0 50 75 14.4 16 19 70 5 100 200 105 20.2 90 135 26.0 57 86 20.2 19 21 80 5 120 230 120 28.4 105 158 37.2 Working Load Limit (kN) Tension, Na Concrete compressive strength, f’c 20 MPa 32 MPa 40 MPa 3.1 3.9 4.3 5.1 6.4 7.2 7.6 9.7 10.8 5.3 6.7 7.5 9.9 12.6 14.1 14.6 18.4 20.6 8.2 10.3 11.5 11.4 14.4 16.2 14.7 18.6 20.8 11.0 14.0 15.6 15.5 19.6 21.9 20.3 25.7 28.8 * For shear loads acting towards an edge or where these minimum dimensions are not achievable, please use the simplified strength limit state design process to verify capacity. 9.2 DESCRIPTION AND PART NUMBERS Anchor size, db (mm) 10 13 16 19 9.3 Part No. Zn BAC06060 BAC06075 BAC06100 BAC08075 BAC08100 BAC08140 BAC10090 BAC10125 BAC12085 BAC12115 BAC12150 Effective depth, h (mm) h = Le - t t = total thickness of material(s) being fixed ENGINEERING PROPERTIES - Carbon Steel Anchor size, db (mm) 6.5 10 13 16 19 62 Effective length, Le (mm) 47 62 87 59 84 124 71 106 63 93 128 Bolt stress area, As (mm2) 20.2 43.2 77.8 134.4 196.0 Bolt yield strength, fy (MPa) 640 680 680 680 680 Bolt UTS, fu (MPa) 800 830 830 830 830 Section modulus, Z (mm3) 12.9 40.0 97.0 219.8 387.2 Mechanical Anchoring Strength Limit State Design 9 Boa™ Coil 9.4 STEP 1 Select anchor to be evaluated Table 1a Indicative combined loading – interaction diagram Design tensile action effect, N* (kN) 60 Notes: ~ Shear limited by steel capacity. ~ Tension limited by concrete cone capacity. ~ No edge or spacing effects. ~ f'c = 32 MPa 50 40 30 19 20 16 13 10 10 0 0 10 20 30 40 50 60 70 80 90 Design shear action effect, V* (kN) Table 1b Absolute minimum edge distance and anchor spacing values, em and am (mm) Anchor size, db (mm) Edge distance, em e ≥ 6 db Anchor spacing, am e < 6 db 10 50 80 100 13 65 105 130 16 80 130 160 19 95 150 190 Step 1c Calculate anchor effective depth, h (mm) Refer to “Description and Part Numbers” table on page 62.

Benefits, Advantages and Features Fast and easy to install: ~ Simply screws into hole. Fast and easy to remove: ~ Screws out leaving an empty hole with no protruding metal parts to grind off. Close to edge and for close anchor spacing: ~ Does not expand and burst concrete. Principal Applications ~ Pallet racking. ~ Temporary safety barriers. ~ Conveyors. ~ Pipe brackets. ~ Gate hinges into brickwork. ~ Temporary hand rails. ~ Bottom plates. Installation 1. Drill hole to correct diameter and depth. Clean thoroughly with brush. Remove debris by way of vacuum or hand pump, compressed air etc. 2. Using a socket wrench, screw the AnkaScrew™ into the hole using slight pressure until the self tapping action starts. 3. Tighten the AnkaScrew™. If resistance is experienced when tightening, unscrew anchor one turn and re-tighten. Ensure not to over tighten. 4. For optimum performance, a torque wrench should be used. 79 11 Mechanical Anchoring AnkaScrew™ Installation and Working Load Limit performance details Anchor size, dh (mm) 6 8 10 12 Installation details Drilled hole Fixture hole Anchor Tightening diameter, dh diameter, df effective torque, Tr (mm) (mm) depth, h (mm) (Nm) 30 6 8 37 25 45 40 8 10 50 40 60 50 10 12 62 60 75 60 12 15 75 80 90 Minimum dimensions* Edge Anchor Substrate Shear, Va distance, ec spacing, ac thickness, bm (mm) (mm) (mm) f’c > 20 MPa 55 3.7 25 50 62 4.1 70 4.5 65 5.6 35 70 75 7.0 85 8.4 75 9.5 40 80 87 11.6 100 13.8 85 12.9 50 100 100 14.8 115 16.7 Working Load Limit (kN) Tension, Na Concrete compressive strength, f’c 20 MPa 25 MPa 32 MPa 2.0 2.4 2.6 2.6 3.0 3.3 3.2 3.8 4.1 3.0 3.6 3.9 4.1 4.8 5.2 5.2 6.1 6.6 4.4 5.1 5.6 5.9 7.0 7.5 7.7 9.1 9.8 6.2 7.3 7.9 8.6 10.2 11.0 11.3 13.3 14.4 * For shear loads acting towards an edge or where these minimum dimensions are not achievable, please use the simplified strength limit state design process to verify capacity. 11.2 DESCRIPTION AND PART NUMBERS Anchor size, db Part No. Effective length, Le (mm) Hex Head Hex Flange Csk Pozi Csk Internal Hex 50 75 100 60 75 100 60 75 100 150 75 100 150 – – – AS08060H AS08075H AS08100H AS10060H AS10075H AS10100H AS10150H AS12075H AS12100H AS12150H AS06050H AS06075H AS06100H – – – – – – – – – – AS06050F – – – – – – – – – – – – – – – – AS08075F – – – – – – – – 6 8 10 12 Effective depth, h (mm) h = lesser of Le - t, 5 * dh t = total thickness of material(s) being fixed 11.3 ENGINEERING PROPERTIES Anchor size, dh (mm) 6 8 10 12 80 Stress area, As (mm2) 22.9 42.4 69.4 84.1 Yield strength, fy (MPa) 640 640 640 640 UTS, fu (MPa) 800 800 800 800 Mechanical Anchoring Strength Limit State Design 11 AnkaScrew™ 11.4 STEP 1 Select anchor to be evaluated Table 1a Indicative combined loading – interaction diagram Design tensile action effect, N* (kN) 25 Notes: ~ Shear limited by steel capacity at h = 7.5 dh ~ Tension limited by the lesser of carbon steel capacity and concrete capacity at h = 7.5 dh No ~ edge or spacing effects. ~ f'c = 32 MPa 20 15 12 10 10 8 5 6 0 0 5 10 15 20 25 30 35 Design shear action effect, V* (kN) Table 1b Absolute minimum edge distance and anchor spacing values, em and am (mm) Anchor size, db e m, a m 6 20 8 25 10 30 12 35 Step 1c Calculate anchor effective depth, h (mm) Refer to “Description and Part Numbers” table on page 80.

This makes chemical anchoring ideal for close to edge fixings or for close anchor spacings. The superior bond of ChemSet™ chemical anchors makes them ideal for installing starter bars, because the required pull out strength is achieved in shallower holes than is possible with cementitious mortars. The polymer matrix of ChemSet™ chemical anchors makes them ideal for cyclic load cases and vibrating loads, such as those encountered in machinery and heavy plant hold down. The Ramset™ ChemSet™ range of chemical anchoring systems provide different options of cost and performance for the designer and for the applicator. For the designer, selection of the correct chemical anchoring solution to his or her design problem will often be based upon the strength capacity of the system, but may also involve issues such as chemical resistance. The following section introduces the designer and/or engineer to the components of the ChemSet™ chemical anchoring range and provides information to allow selection of the anchor with the right capacity for various environmental conditions. The superior strength of grade 5.8 carbon steel threaded stud anchors gives the ChemSet™ chemical anchor systems greater steel capacity than regular grade 4.6 threaded rod.

Anchoring into pre-manufactured masonry units such as concrete blocks, wire cut extruded clay brick and pressed solid bricks requires a different approach to anchoring into solid in-situ concrete or precast concrete units. The anchor must firmly clamp a fixture to the face of the substrate without splitting it or causing other damage. The capacity of the anchors is frequently limited by the strength of the substrate, and the strength of the various units available on the market varies from manufacturer to manufacturer and from region to region within any one manufacturer. Also being discrete units rather than a continuous slab means the anchor will always be in close proximity to an edge of that individual unit whilst also possibly being centrally placed within the overall structure. Ideally all anchors into these pre-manufactured masonry units should be in the centre of the block or brick and in the case of hollow units such as wire cut bricks and concrete blocks the anchors should be placed in the solid section of the unit, but it is not always practical to position fixtures to ensure this. This section provides performance information to aid design of connections to pre-manufactured masonry units. It assists design by recognising that positioning anchorage points in the centre of a masonry unit is not always possible by providing capacities for zones rather than specific points and we have also endeavoured to provide a realistic evaluation of the anchor’s performance in the poorest performing section within these zones. 148 Please note that as the performance information on pre-manufactured masonry substrates is provided by the various manufacturers in Working Load Limit format our anchor performance data in this section is also provided in Working Load Limit format. For lightweight applications into Brick and Block a number of alternate Ramset™ Concrete Anchors may be considered. 1. ShureDrive™ (see page 105 – Mechanical Anchoring section). 2. EasyDrive Nylon Anchors (see page 109 – Mechanical Anchoring section). The performance of the above anchors is not dependent on the substrate and therefore you may refer to the performance figures detailed in the Mechanical Anchoring section. 23 Brick and Block Anchoring 23.1 TYPICAL PRE-MANUFACTURED MASONRY UNITS 23.1.1 TYPICAL DIMENSIONS CONCRETE BLOCK – Overall CLAY BRICK – Overall 76 mm 190 mm 110 mm 230 mm 190 mm SOLID BRICK 390 mm CONCRETE BLOCK THREE HOLE BRICK Nominal 115 mm Nominal 138 mm Nominal Wall Thickness 32 mm Nominal Hole Dia. 46 mm Nominal Wall Thickness 25 mm Nominal Wall Thickness 37.5 mm Note: Due to the manufacturing process, the internal cavities have tapered walls.

Careful selection of product raw materials and tight manufacturing tolerences ensures that reliable, consistent performance is available from our load bearing components. The Ramset™ Concrete Lifting System provides the same high level of product quality, expertise and service to the tilt panel and precast concrete industry that other segments of the construction industry have come to expect from Ramset™. Product is manufactured in accordance with our accreditation to and with the requirements of the AS/NZS ISO 9001:2000 Quality Management Systems standard. Versatile Tested ™ Ramset Concrete Lifting Systems are optimised for use with a wide range of standard precast sections, from wall panels to bridge beams, columns to culverts. Quick The Ramset™ Concrete Lifting Systems are designed for speedy coupling/uncoupling of the lifting clutches from the lifting anchors, thus eliminating costly delays during the lifting process. Safe Safety is not a luxury with the Ramset™ Concrete Lifting Systems. Each part of the system is intended to compliment the other. Multiple levels of safety redundancy are available when the system is used correctly. 188 Quality Significant test programs are conducted to verify product integrity under a wide range of conditions and rigorous statistical analysis ensuring that published capacity data is representative of the true spread of results achieved in testing and the expected variability within the total product population. Expertise With specialist Sales Engineers located in all the major capital cities, Ramset™ have an unparalleled commitment to the Concrete Lifting Industry, each Engineer having an intimate understanding of local requirements. Design assistance is available from our Engineers in order to help fully realise the benefits inherent in the Ramset™ Concrete Lifting Systems. 32 LIFTING TECHNOLOGY 32.1 IMPORTANT NOTICE The information presented in this section will prove a useful tool to all involved in the production of precast concrete elements, however it must be recognised that the capacity information is intended for use by suitably experienced and/or qualified persons only. Load cases can involve complex calculations and require a number of separate design checks to be carried out to fully represent the situation at hand. Given the number of variables that determine the validity of a particular systems suitability for a given scenario, the information presented will allow a design professional to fully consider all aspects relevant to the derivation of both the load case(s) and the capacity and hence recommend a system solution. The designer is encouraged to contact their local Ramset™ specialist Sales Engineer if additional information or advice is required. The capacity obtained from load bearing components will be influenced by the concrete’s (tensile) strength, element geometry, load direction and component orientation within the element. 189 32 32.2 Lifting Technology LIFTING ANCHORS All lifting anchors produced by Ramset™ comply with the requirements of AS3850 - 2003. Lifting anchor capacities detailed herein are based on test results achieved in plain (unreinforced) or nominally reinforced (light central mesh) concrete. This standard requires that: ~ components are produced from ductile materials. ~ a minimum Factor of Safety of 2.5 : 1 is achieved when the product is used as instructed. When loaded to their full design working load capacity, lifting anchors may be used a maximum of 10 times. Testing has confirmed that whilst structural reinforcement is required to prevent substrate member or section failure, it will have negligible influence on lifting anchor capacity apart from offering additional ductility during overload events. Component reinforcement as detailed herein must be securely fixed to the lifting anchor to ensure intimate contact between them. If loaded to 60% of their design working load capacity, lifting anchors are re-usable to the same extent as the lifting clutches. Lifting anchors must not be re-worked in any way, i.e. welding, cutting, bending etc., as this may seriously alter the anchors structural integrity. If it is considered necessary to alter a lifting anchor physically in any way, please contact your local Ramset™ specialist Sales Engineer for appropriate advice. 32.3 LIFTING CLUTCHES Ramset™ lifting clutches are a critical part of the load bearing equipment involved in the lifting of concrete elements and hence should be treated with appropriate care. All Ramset™ lifting clutches are initially proof tested in accordance with the requirements of AS3850 - 2003 and there after must be proof tested at twelve monthly intervals to ensure compliance with this standard. Please contact your local Ramset™ specialist Sales Engineer for advice regarding the testing of your clutches. 190 Ramset™ lifting clutches are designed to be operated by hand, either directly or with the aid of a remote release line on appropriate models, hence if excessive force is required to operate any Ramset™ lifting clutch a fault condition is indicated and the cause of the fault should be investigated. Please contact your Ramset™ specialist Sales Engineer for advice regarding the servicing of your lifting clutches. Under no circumstances shall any modification be performed on any lifting clutch unless written approval is obtained from Ramset™. Lifting Technology 32.4 SUBSTRATE SUITABILITY It is recommended that a minimum concrete compressive strength of 15 MPa is available at time of lift. Concrete compressive strength is referenced as it is the most widely available (and readily obtained) data for concrete mixes. Curing rates are dependant on a number of factors, however it should be recognised that mid winter curing will take longer than during warmer months. In order to ensure adequate concrete strength is available at time of lift, consider the use of higher strength concrete, a modified high early strength concrete, steam cure, prolonged curing time or a combination of these methods. The lifting anchor capacity data therefore is valid for normal weight concretes having a tensile strength/compressive strength relationship consistent with that of traditional sand/cement/aggregate mixes, i.e. f’cf = 0.6 * Lf’c. Whilst the capacity data refers to concrete compressive strength, it should be recognised that lifting anchor capacity is actually governed by the concrete’s tensile strength. 32.5 32 If the concrete being utilised varies from this relationship (for example due to the addition of modifiers like fly ash), the equivalent concrete compressive strength should be determined after consultation with the concrete mix/admixture supplier. This is especially important if it is believed that the modifiers will delay or retard the generation of concrete tensile capacity.

Cone of Failure a a a Anchors INTERFERENCE BETWEEN CONCRETE CONES ac = Specified for each anchor, see anchor type where: ac = critical spacing At the critical spacing, the capacity of one anchor is on the point of being reduced by the zone of influence of the other anchor. Ramset™ anchors placed at or greater than critical spacings are able to develop their full tensile loads, as limited by concrete cone or concrete bond capacity. Anchors at spacings less than critical are subject to reduction in allowable concrete tensile loads. Working loads on anchors spaced between the critical and the absolute minimum, are subject to a reduction factor "Xna", the value of which depends upon the position of the anchor within the row: Nar = Xna * Na where: Nar = reduced ultimate tensile load concrete ac a Cone of Failure Anchors ANCHORS IN A ROW 194 32 Lifting Technology For anchors influenced by the cones of two other anchors, as a result for example, of location internal to a row: 32.7.4 CRITICAL EDGE DISTANCE Xnai = a / ac ≤ 1 At the critical edge distance for anchors loaded in tension, reduction in tensile loads just commences, due to interference of the edge with the zone of influence of the anchor. where: The critical edge distance for cast-in anchor is taken as: Xnai = spacing reduction factor for an anchor internal to row a = actual spacing (mm) ec = Specified for each anchor, see anchor type where: Unequal distances ("a1" and "a2", both < ac) from two adjacent anchors, are averaged for an anchor internal to a row: ec = critical edge distance Xnai = 0.5 (a1 + a2) / ac ec Anchor If the anchors are at the ends of a row, each influenced by the cone of only one other anchor: 2*ec Cone of Failure Xnae = 0.5 (1 + a / ac) ≤ 1 where: Xnae = spacing reduction factor for an anchor at end of row INTERFERENCE OF EDGE WITH CONCRETE CONES If the edge lies between the critical and the absolute minimum distance from the anchor, the concrete tensile load reduction coefficient "Xe", is obtained from the following formula: Xe = 0.3 + 0.7 * e / ec ≤ 1 where: Xe = edge reduction factor tension Critical edge distances define critical zones for the placement of anchors with respect to an edge. The critical edge zone has a width equal to the critical edge distance. The concrete tensile strengths of anchors falling within the critical zone are reduced.

Casting panels in an exposed environment however requires that all equipment used is capable of surviving the often punishing conditions presented, it is with this in mind that the Ramset™ Systems For Site Cast Wall Panels have been designed. Ramset™ Systems For Site Cast Wall Panels are simple to place and use and are tolerant of the conditions inherent with site casting, helping to protect the project timeline and thus offer benefits far in excess of the initial component cost outlay. 202 Cast-In Lifting Site Cast 34.1 34 APPLICATIONS 34.1.1 FACE LIFT APPLICATIONS Scenario: Tilting panel from casting bed. Attributes: ~ Suction. ~ Concrete strength. ~ Out of plane rotation of panel. ~ Tensile loaded lifting anchors. ~ Element will hang out of plumb. ~ Centre of gravity dictates off plumb angle. ~ Braking forces of crane – dynamic loads. Solution: Ramset™ Face Lift System. Careful attention should be paid to the orientation of the face lift anchors in the panel. Arrow markings on the face lift anchors shows the correct orientation of the anchor with respect to the top and bottom of the panel. If it is found that the anchors are placed incorrectly, i.e. the arrow markings point to left and right rather than to top and bottom, advice should be sought from your local Ramset™ specialist Sales Engineer prior to lifting. 34.2 INSTALLATION Lifting Clutch Void Former Arrow markings must point to top and bottom of panel. Face Lift Anchor with Bar Clip Mesh 2 x N12 x 300 mm cross bars required for 125 mm to 150 mm thick panels. Note: Orientation of anchor must be correct. 203 34 34.3 Cast-In Lifting Site Cast ANCHOR TYPES 34.3.1 FACE LIFT ANCHOR Benefits, Advantages and Features Convenient: Sizes available to suit panel thicknesses of: ~ Bar clip floats with mesh to prevent anchor movement when trafficked. ~ 125 mm ~ 130 mm ~ 150 mm ~ 170 mm ~ 175 mm ~ 180 mm ~ 200 mm Durable: ~ Zinc Plated Steel Insert for economical interior protection. ~ Steel Insert is Grade 350 steel in accordance with AS3678 - 1996. ~ Engineered plastic base prevents rusting. ~ Strong, stable design withstands trafficking.

Components can vary greatly in both size and shape and it is therefore important that the systems utilised are ‘scalable’ to handle these variations and yet still offer a consistent installation method. The Ramset™ Systems For Component Precast meet this requirement and additionally represent one of the simplest solutions for the production of pipes, pits, lids, culvert sections, stairs, plats, columns and beams. 206 Cast-In Lifting Component Precast 35.1 35 APPLICATIONS 35.1.1 PINHEAD APPLICATIONS Scenario: Lifting of item from casting location/removal to stack location. Attributes: ~ Even load distribution ensured by sling configuration. ~ Suction. ~ Concrete strength. ~ Tensile loaded lifting anchors (in plane of component). ~ Transitional movement of component (no out of plane forces). Solution: Ramset™ Pinhead System. Scenario: Fixed sling lifting of item. Attributes: ~ Non preferred method. ~ Suction. ~ Cannot guarantee load distribution to 4 legs of sling, i.e. must design for load to 2 legs only. ~ Shear load component acting on lifting anchors towards unrestrained free edge of component. ~ Requires additional restraining reinforcement. Solution: Ramset™ Pinhead System. Applications continued on next page. 207 35 Cast-In Lifting Component Precast Scenario: Inverting a component. Attributes: ~ Complex load cases. ~ Internal formwork. ~ Suction. ~ In plane rotation. ~ Multiple handling required. Solution: Ramset™ Spread Anchor System. Where possible, lifting anchors and rigging should be configured to ensure that shear loads toward edges are minimised or eliminated as they will require additional restraining reinforcement detail and will have less capacity than for lifting anchors loaded in tension. This can be achieved through the use of spreader bars and careful consideration of load case/rigging orientation. 208 Cast-In Lifting Component Precast 35.2 35 INSTALLATION 35.2.1 PINHEAD FOOT ANCHOR SYSTEM Pinhead Lifting Clutch 35.2.2 PINHEAD EYE ANCHOR SYSTEM Pinhead Lifting Clutch Pinhead Void Former Pinhead Void Former Pinhead Foot Anchor Pinhead Eye Anchor Tension Bar 35.2.3 SPREAD ANCHOR SYSTEM Lifting Clutch Support Plate Void Former Spread Anchor Tension Bar 209 35 35.3 Cast-In Lifting Component Precast ANCHOR TYPES 35.3.1 PINHEAD FOOT ANCHORS 35.3.3 PINHEAD COMBINED ANCHORS Benefits, Advantages and Features Benefits, Advantages and Features Economical: Reliable: ~ Simple design provides cost effective lifting of large sections. ~ Added reliability of foot in combination with component reinforcement. ~ Easy verification of anchor, as load range and length is visible when cast.
