Behaviour of fixed-ended thin-walled steel channel columns with complex stiffeners

Abstract

This thesis presents experimental and numerical investigations of fixed-ended cold-formed steel channel columns with complex-stiffeners. The complex stiffeners of the sections consist of simple lips with return lips. The channels are considered as thin-walled structural members. A series of channel columns with complex stiffeners having four different cross-section size were tested over a range of column lengths.
