The Steel Construction Institute (SCI) has
completed designing a software programme
for Ireland-based steelwork contractor
Kiernan Structural Steel, covering
fabricated girders with sinusoidal beam
webs, commonly known as SIN beams.
“The new SIN beam design software
enables consulting engineers and steelwork
contractors to quickly design plate girders
with a corrugated web; taking into account
restraint conditions, end moments and
deflection limits. This allows the designer
to quickly determine whether the SIN
beam could be a cost-effective solution in
potential scenarios such as roof rafters,
mezzanine floor beams and footbridges,”
said Kiernan Structural Steel Sales Manager
Paul Watson.
The sinusoidal profile stiffens the
web, meaning thin material can be
used, reducing the weight of the section.
Design rules are given in Annex D of
BS EN 1993-1-5, which identifies the flanges
to carry the bending moment and any axial
force, and the web to carry the shear.
Lateral torsional buckling between
restraints uses the simplified rules in BS
EN 1993-1-1 clause 6.3.2.4. Both bending
deflection and shear deflection is calculated
by the software and compared with userdefined
limits.
The beam itself may be tapered or of
uniform depth, with the opportunity to
apply UDLs, point loads, end moments
and axial forces. Restraints may be added
to either flange independently or a fully
restrained flange specified. The individual
components of the beam may be verified
separately or the lightest weight flanges and
web automatically selected.
“The wide range of applied loading and
the requirement to verify the member
between user-defined restraint positions
would lead to laborious hand calculations
making a software solution very attractive,”
said SCI Associate Director David Brown.
“Alternative member cross sections can
be examined immediately to identify an
efficient solution, with automatic lowest
weight solutions found for a given beam
depth.”
The software has been written to
accommodate design to the UK National
Annex or the Irish National Annex.

East Ayrshire Council has signed
up Morrison Construction to
construct a new £59M learning

Cumnock. The project is said
to be one of Scotland’s largest
and most ambitious education
projects through a two-stage
design and build process. The
steel-framed complex will consist
of four linked structures up to
three-storeys high, three school
pavilions and a sports centre.
Cheshire County FA, in
partnership with Cheshire West

its intention to open a unique
world-class football facility in
Northwich, Cheshire. The site will
become a leading centre for the
provision of women and girls
football and Cheshire County
FA has also confirmed that it is
in discussions with a Women’s
Premier League club to become a
partner on what will be a ‘best in

The event saw seven staff

travelling a total of 50km on the
River Thames.

Design software for
SIN beams now available
Installation complete for Taplow bridge
Site work has now been completed for a new
River Thames footbridge designed by Knight
Architects and structural engineers COWI at
Taplow in Buckinghamshire.
Berkeley Homes is the client for the
project, which will provide a new pedestrian
link in the Thames Path to connect the
new Taplow Riverside development with
Maidenhead.
The shallow arch form of the design is
inspired by Brunel’s nearby Maidenhead
Bridge and is echoed in the slender steel box
structure.
Fabricated triangular-section box girders
form the twin structural arches that support
the deck. Slender steel plate hangers complete
the composition and ensure the structure is
lightweight and transparent in river views.
Working on behalf of main contractor
Land & Water, fabrication of the bridge
sections was undertaken by S H Structures
(SHS).
SHS site-assembled the 39m-long, 38t
footbridge, having brought it to site in
sections. Land & Water then lifted it onto a
barge so it could be taken along the river and
then rotated into position.
