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.

DESIGN PROCESS
This information is provided for the guidance of qualified
structural engineers or other suitably skilled persons in the
design of anchors. 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.

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.

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.

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.

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.

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

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

= 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.

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.

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

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

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.
Having installed and run the program proceed to the toolbar at
the top of the screen and select the "New" button, this will
bring you to the first of four input screens.
Project/Customer Details
The program attempts to acquire the minimum data needed to
fully specify the anchoring problem,
~ substrate details
~ adverse environments
~ interfering edges and anchors
~ load case information
On the first screen (Fig. 1) enter Project/Customer Details.
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.

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.

TECHNOLOGY
DERIVATION OF CAPACITY
6.1
Internationally, design standards are 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.

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.

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.

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.

CONCRETE CONE FAILURE MODE

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.

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.

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.

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

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.

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.

DESIGN
6.4.1 WORKING LOAD DESIGN
6.4.2 STRENGTH LIMIT STATE DESIGN
Using the permissible stress method which is still valid in
many design situations:
Designers are advised to adopt the limit state design approach
which takes account of stability, strength, serviceability,
durability, fire resistance, and any other requirements, in
determining the suitability of the fixing. 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

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

(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.

The appropriate concrete compressive strength "f’c" is the actual

method) for anchors are obtained from:
Nac = Nuc / 3.0

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.

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:

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:

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:

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

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:

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

Characteristic ultimate bending capacities (Mu), are obtained
from the following formula:

ANCHOR GROUPS
This information deals specifically with the design of individual
anchors, loaded either as a single anchor or as a member of
a group. 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.

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.

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.

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

the value of the total spring rate for the anchor/fixture/base
material system.

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.

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.

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”.

FIRE
When exposed to heat so that it reaches a temperature of
about 550°C, steel retains about half of its original strength.
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.

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.

Product
The HiShear™ 8.8 Anchor is a heavy duty, torque setting
expansion anchor.
Benefits, Advantages and Features
Provides same shear performance as larger diameter anchors:
~ Grade 8.8 Steel Bolt and thin spacer.
Faster installation:
Principal Applications
~ Smaller holes are easier to drill.
Same tensile capacity as larger diameter anchors at same depth:
~ Patented sleeve design.
Improved security:
~ Patented sleeve pulls down to close gaps up to 5 mm and induce preload.
Suitable for structural shear loads:
~ Raker angles to concrete panels.
~ Rafters to concrete panels.
~ Heavy structural steel to concrete.
~ Corner guards.
~ High tensile capacity Grade 8.8 Steel Bolt.
~ High tensile washer to resist dishing.
“Safety Yellow” coloured head:
~ Easy identification during inspection.
Faster installation:
~ Through fixing eliminates marking out and repositioning of fixtures.
Installation
1. Use the fixture as a template and drill the hole
to the correct diameter and depth as per the
installation specifications.
2. Clean hole thoroughly with brush. Remove
debris by way of a vacuum or hand pump,
compressed air etc.
3. Insert HiShear™ 8.8 through fixture, tap lightly
with hammer until washer contacts fixture.
4. Tighten HiShear™ 8.8 anchor to specified
assembly torque using torque wrench or
impact wrench (rattle gun).

GENERAL INFORMATION
PERFORMANCE RELATED
MATERIAL
INSTALLATION RELATED
Product
The Boa™ Coil Anchor is a heavy duty, rotation 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.)

The TruBolt™ Anchor is a heavy duty, torque setting
expansion anchor.
Benefits, Advantages and Features
Maximum shear capacity for hole size:
~ Stud diameter equals hole diameter.
Faster installation:
~ Through fixing eliminates marking out and repositioning of fixtures.
High clamp load:
~ Stud design ensures pull-down on fixture.
Superior corrosion resistance:
~ AISI 316(A4) Stainless Steel.
Outstanding exterior durability:
~ 42 micron Hot Dip Galvanised coating.
Superior strength:
Principal Applications
~ Structural beams and columns.
~ Anchoring braces for precast panels.
~ Bottom plate and batten fixing.
~ Formwork support.
~ Installing signs, handrails,
balustrades and gates.
~ Safety barriers.
~ Cold forged steel construction.
Installation
1. Use fixture as a template, drill a hole the same diameter as the TruBolt™.
2. Remove debris by way of a vacuum or hand pump, compressed air, etc.
Drive anchor into hole until washer is flush with the fixture.
3. Tighten with a spanner. For optimum anchor performance a torque
wrench should be utilised.

ENGINEERING PROPERTIES - Carbon Steel
Anchors with strengths higher in the reduced section than
in the threaded section, are formed by cold working. The
reduced section is located under the expansion sleeve.
For shear loads, the critical plane is located in the threaded
section, and for tensile loads, the critical plane is located at
the reduced section.

Product
The AnkaScrew™ Anchor is a medium duty, rotation setting
thread forming anchor.
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.

Mechanical Anchoring Notes

CHEMICAL
ANCHORING
OVERVIEW
The key feature of ChemSet™ chemical anchors is that they do
not impart an expansion stress on the surrounding substrate.
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.

BRICK BLOCK
AND
ANCHORING
OVERVIEW
Ramset™ provides a range of concrete anchors for anchoring
into pre-manufactured masonry units from lightweight fixtures
to heavy structural connections including stud types and hex
bolt finishes.
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.

TYPICAL BOLT PERFORMANCE INFORMATION
Tabulated below are nominal reduced ultimate
characteristic capacities for bolts manufactured in
accordance with ISO 898-1.
It is recommended that Stainless Steel bolts be lubricated and
that tightening torque be applied in a smooth, continuous
manner. Impact wrenches (rattle guns) are not suitable for the
tightening of Stainless Steel fasteners.
The expected capacity of bolts should be independently
checked by the designer based on the bolt manufacturers
published performance information.

CAST-IN
ANCHORING
OVERVIEW
Whether an application calls for precast or cast in-situ
components, there is a suitable Ramset™ Cast-In Ferrule for
almost every design case.
Not only does Ramset™ offer reliable, quality product,
Ramset™ understands the importance of supporting the
product with technically superior design information, such as
this resource 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 Cast--In Ferrules.
Care should be taken to remember that the performance data
contained herein relates to the Ramset™ range of Cast-In
Ferrules and hence should not be used to justify a generic
replacement that may appear physically similar, as the actual
performance will be heavily influenced by the steel grade and
manufacturing tolerences.
162
The Ramset™ Cast-In Ferrule range is available in Zinc, Hot
Dipped Galvanised and Stainless Steel finishes to cater for a
wide range of atmospheric conditions. Sizing from M10
through M24 allows for economical designs to be derived,
with appropriate accessories providing a high degree of
installation flexibility.
The following section introduces the designer and/or
engineer to the Ramset™ Cast-In Ferrule range and provides
performance information to allow selection of the right Cast-In
Ferrule for the job.

LIFTING
OVERVIEW
Since 1988, Ramset™ have been manufacturing and
supplying solution driven systems for the purpose of safely
lifting precast concrete units.
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.

32.1
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.

when top lifting, apply the formula below, in which:
α
Greater of:
Li TOP = (W + H) * K
Pn
Angle
or
Li TOP = W * D * K
Pn
Li
= Load applied at each lifting point (t)
W
= Self weight of the unit (t)
H
= Demoulding suction of the unit (t)
D
= Dynamic loads expected due to handling co-efficient
K
= Angle at the peak of the slings co-efficient
Pn
= Number of lifting points accepting the load case
K =

Edge Lift Anchor Load Formulae
For determination of edge lift forces on anchors during lift from
horizontal:
= 60° then K = 1.16
Greater of:
Li EDGE = (W + H) * K

Example
The formulae are only valid when the anchors are located in
the edge of the panel and the panel is supported on the
opposite edge, about which rotation occurs.
= 0° then K = 1.00
Face Lift Anchor Load Design
Given the wide variations in lifting anchor configuration and
component geometry for face lifted panels, it is recommended
that design software or standard charts be utilised for
calculating lifting anchor forces.

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

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

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. For clarity, the figure includes the prohibited zone as
well as the critical zone.

SYSTEMS FOR
SITE CAST
WALL PANELS
OVERVIEW
Site casting of wall panels is a convenient solution for low
rise structures where adequate site space is available for the
production of panels.
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.

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.

SYSTEMS FOR
COMPONENT
PRECAST
OVERVIEW
The production of precast components offers a unique
challenge for the precaster.
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.

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.

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.
