See moreThis research report describes a test programme conducted into the behaviour 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 tests were closely simulated using a finite element programme thereby validating its use in predicting cold-formed tubular beam-column behaviour. the finite element programme was then used to find the maximum load and moment capacity, for the section tested, at varying ratios of end moment, from which the corresponding maximum second order elastic moments were calculated. the results of this numerical investigation are compared with the relevant interaction design rules from AS4100 (Standards Australia (1990)) and the AISC-LRFD specification (1986).
