RIDBA helps reduce the cost of agri buildings
The potential for the cost of erecting agricultural buildings to rise due to European legislation has been minimised by
RIDBA, the Rural and Industrial Design and Building Association.
IDBA has for some time
now been working on
revising Eurocodecompliant load tables for
steel portal frames for use
in Class 2 Agricultural
Buildings. These are now
complete and will help steel frame
manufacturer corporate members
of RIDBA to reduce their costs in
fabricating agricultural buildings as
they may not need to employ a
structural engineer to design every
one.

The revised load tables in
accordance with BS 5502-22:2003
+ A1:2013, “Buildings and
structures for agriculture — Part
22: Code of practice for design,
construction and loading” have
been expanded to provide more
efficient designs for a greater
range of portal frame steel
buildings.
They now cover four load
situations, ranging from the worst
case for Class 2 agricultural
buildings of Snow Load 4 at 200m
to a low loading of Snow Loading
2 at 100m. They also cover two
intermediate loadings at Snow
Load 3 at 100m one with 24m/s
basic wind speed and the other
with 22m/s basic wind speed.
This large range of loadings
means that a high proportion of
agricultural buildings from Lands
End to John O-Groats can be
more efficiently designed.
The revised load tables do not
just provide the steel sizes but also
details of wall and roof bracing,
eaves struts, connections, base
plates, haunches, subgrade
information and revised timber
purlins, rails and eaves beams
information.
