Abstract

This paper 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 simulated using a finite element programme. This finite element programme was used to find maximum second order elastic moments, for the section tested, at varying ratios of end moment. The results of this numerical investigation are compared with the relevent interaction design rules from AS4100 (Standards Australia (1990)) and the AISC-LRFD specification (1986).

Behaviour of Cold-formed SHS Beam-columns

Saint Louis, Missouri

This paper 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 simulated using a finite element programme. This finite element programme was used to find maximum second order elastic moments, for the section tested, at varying ratios of end moment. The results of this numerical investigation are compared with the relevent interaction design rules from AS4100 (Standards Australia (1990)) and the AISC-LRFD specification (1986).
