OVERVIEW
Key features
The ASDO system is the only tie-rod and compression-rod system that
holds an ETA for nominal sizes up to M160
Fork connectors of cast steel in conjunction with high-strength tie-rod enable
design resistance up to 9,568 kN
Uniform fork connector design for all nominal sizes
Identical system components and connection dimensions for carbon steel and stainless
steel version
FEM-supported fork connector design with almost homogeneous tension distribution
Pin locking cap is flush with the fork connector contour
Single rod lengths up to 22m possible
Simple visual checking of minimum thread engagement
The Construction Products Regulation of 2011 (CPR) came into force July 2013 making it mandatory for tension bars supplied
within the European Union to be supplied CE marked indicating they meet the requirements of European harmonised design
codes and are ‘fit for purpose’.
ASDO structural tie bars have met this requirement since 2004 and are manufactured under ISO 9001 and EN1090 independently
audited quality systems. This has allowed Anker Schroeder to successfully supply many projects around the world.

GENERAL
INFORMATION
ASDO540-S M90 tie bars are used as hangers on this East London Line
railway bridge in Shoreditch. As well as undergoing rigorous QA the
system was also fatigue tested to 2m cycles.
ASDO540-S M56 tie bars were used to form the tension elements for this bowstring truss Kåkenhus footbridge in Norrköping, Sweden.

Notes for tables 3 & 4:
1. Design tensile resistance Ft,Rd = min {fy x Ag / γM0; 0.9 x fua x As / γM2} as per EN1993-1-8 with partial factors γM0 = 1.0 & γM2 = 1.25 for carbon steel and γM0 = 1.1 & γM2 = 1.25 for stainless steel according EN1993-1-4
2. For the full design resistance to be utilised connection plates must be fabricated from S355J2 to EN10025 (or equivalent) and to minimum dimensions given in table 5
3. All threads are cut threads and are not suitable for dynamic loads. Rolled threads with higher fatigue resistance can be made on request - please contact our technical department
4. For full design capacity threads must be engaged at least 1.2 x thread diameter, see installation guide page 17
5. Stainless steel bar grades M12-M42 are austenitic 1.4401/4, M48+ are duplex 1.4462.

Corrosion protection
ASDO systems can be supplied self colour or galvanised as standard. Sizes up to M42 are supplied with forks, pins, turnbuckles,
couplers and thread-cover sleeves hot dip galvanized as standard.
Note ASDO540-S bars M105-M160 are quench and tempered steel
and therefore should not be galvanised.
Bar threads can be formed after galvanising or are re-machined to
size following galvanizing; repairs to the zinc coating are made in
accordance with DIN EN ISO 1461. Spanner flats on the tie-rods are
pressed following hot galvanizing to prevent brittle fracture. Note,
due to the nature of the galvanising process the visual finish of galvanised product is variable. If a high level of aesthetic finish is required systems should be subsequently painted after a suitable
primer has been applied. ASDO tie bars cannot be supplied with
‘top-coat’ finishes, this should be applied by the customer. Please
advise us before placing an order if bars are intended to be painted.
Please contact our technical department for more detail.

ASDO CROSS BRACING
ASDO tie bars bar can be used for cross
bracing in a variety of ways but in all cases
are easy to install and allow for In-Situ length
adjustment to accommodate construction
tolerances. When selecting a bracing system
the accessibility for installation and overall
cost should be considered as well as the
aesthetics. The three most common types
are shown opposite:
ASDO bracing with centre disc
This is the most common system used
as it offers the greatest flexibility and
gives the best length adjustment capabilities. It should be considered that
double the number of clevises are required compared to the other systems.

PRODUCT DATA
ASDO bracing with cross turnbuckle
The cross turnbuckle can offer a more
cost effective alternative to the centre
disc, dependent on size, but gives limited
in-situ adjustment. Further turnbuckles
can be added for greater adjustment.
Two angles are offered, 40° ≤ αCT ≤ 140°
degrees and 60° ≤ αCT ≤ 120° degrees
ASDO bracing with crossed bars
If the tie rods can be offset from each
other (ie are not in the same plane)
then bars can be crossed as above.
This is the most cost effective solution
requiring the least components but has
limited adjustment. Turnbuckles can be
added to provide greater adjustment.

Connection plates
The shape of the connection plate is dependent on the load
transfer to the supporting structure as shown above. It should
be ensured that the correct load path is followed back to the
structure.
The plate should be fabricated in S355J2 grade material according EN10025 with minimum dimensions as per Table 5.
Minimum plate thickness can be built up using welded bosses if
required. Stainless steel connection plates should have a min.
0.2% proof stress equivalent or greater than grade S355 of the
same thickness.
Pin holes must be produced mechanically.
Weld lengths ands sizes should be designed appropriately to
EN1993-1-8.

Assembly
The ASDO system is simple to assemble. Generally tie bars less
than 6m will be delivered fully assembled (pins are packed separately), longer lengths may be split into transportable lengths. On
receipt of goods please check that all components are present
and no damage has occurred to any part of the system, please
contact our technical department if you suspect damage has occurred.
Prior to installation assemble full lengths and adjust to the correct pin-to-pin length. To install simply place the fork over the
connection plates, insert pins and secure and hand tighten the
system by either rotating the turnbuckle (if present) or the bar
(if no turnbuckle).
The pin design varies depending on the nominal size and steel
grade but typically are as shown above. End caps should be
screwed tight using Loctite or similar.
GENERAL
INFORMATION
misalignment
γ ≤ 0.5°
A- A ( 1 : 5 )
Installation
When installing the ASDO system ensure that the maximum
misalignment does not exceed 0.5° from the plane of line of
force as shown above. This prevents bending in the fork connectors and connection plates.
ASDO tie-rod system should be installed with fork ends in the
same orientation and not twisted as shown above.
The bar thread end should be visible through the fork to ensure
full thread engagement
For detailed information on the installation of our tie rods and
the required tools please contact our technical department.
In-Situ stressing and load measurement
ASDO tie bars can be stressed or have their tensile load measured once installed. Specially designed hydraulic rigs can be hired
which allow tie bars to be stressed or have the tensile load they
are carrying measured, contact our technical department for
more detail.
ASDO tie bars can also be supplied with Strainsonic load measuring pins. Using a portable hand-held device ultrasonic signals are
passed through the pin and the time-of-flight is measured using
sophisticated on-board electronics. From instant measurements
of the changes in the ultrasonic signal due to stress in the pin the
‘acoustoelastic’ effect of materials is utilised to determine the
load in the pin.
This provides a robust and accurate (+/-2.5%) method of load
measurement and is self-compensating for temperature effects.

QUALITY ASSURANCE & DESIGN
Dynamic loads
The ASDO system can also be supplied with cold rolled
threads that gives bar threads a much greater resistance to
fatigue than the standard cut thread.
Fatigue tests have been performed on full scale ASDO systems
to over 2m cycles of loading without failing. ASDO do not
recommend hot dip galvanising rolled threads due to the
increased risk of hydrogen embrittlement and much reduced
fatigue resistance.
Please contact our technical department for further information
regarding ASDO systems for use on structures subject to
fatigue.
Design and quality assurance
The ASDO system is manufactured under independently audited
quality systems to ISO 9001 & EN1090 ensuring the requirements of the ETA and CE marking are met.
The ASDO fork (or clevis) was developed using FEM techniques
resulting in a very efficient load carrying design.
Technical drawings / BIM
To assist you in the design process ASDO can supply component data in CAD and BIM format. Links to files can be found on
our website www.asdo.com and a dedicated server ensures the
user always downloads the latest information, for BIM this
includes quality documents, installation manuals, brochures
and design loads.
As most tension systems on the market ASDO fork connectors
are made from cast steel. The ability of castings to transfer
load from the structure to the bar is paramount and Anker
Schroeder have a stringent quality control regime for the casting process. All castings meet the requirements of EN10340.
Enhanced non-destructive testing can be offered by agreement.
Please call our technical department for more detail.
For CAD users we offer 2D and 3D files which contain most of
the components shown in this brochure. Individual components
can be arranged into assemblies as required, only the individual
tie rod length (see page 9) and restrictions to the angle of cross
bracings (see page 12) need to be adapted to your project needs.
See www.asdo.com for more detail.

Sustainability
Steel is the most recycled material in construction. All anchorage material supplied by Anker Schroeder is
sourced from reputable steel mills and, where possible, up to 90% of melt is recycled steel. Once a structure has reached the end of it’s design life Anker Schroeder bars are 100% recyclable as scrap material.
