Behaviour of Cold-Formed SHS Beam-Columns
This research report describes a test program conducted into the behavior of cold-formed, compact square hollow section beam-columns. The tests were conducted in a purpose built test rig capable of applying load and moment in a constant ratio. The test specimens were pin-ended specimens loaded, with varying load/moment ratios, at two different ratios of end moment. The results of the test were closely simulated using a finite element program thereby validating its use in predicting cold-formed tubular beam-column behavior. The finite element program was then used to find the maximum load and moment capacity, for the section tested, at varing ratios of end moment, from which the corresponding maximum second order elastic moments were calculated. The interaction design rules from AS4100 (Standards Australia (1990)) and the AISC-LRFD specification (1986).
