This paper describes an experimental investigation into the behaviour
of cold-formed steel intermediately stiffened plates which are subject
to pure compression and cold-formed beams with intermediately stiffen
ed compression elements which are subject to bending. Each plate or be
am has a central intermediate stiffener The investigation is concerned
with the performance of the intermediately stiffened elements with di
fferent degrees of rigidity provided by the stiffener. The ultimate lo
ads are compared with the predictions of BS 5950 Part 5 Code and the f
irst Draft Eurocode 3.
