- Abstract
- This study presents a numerical investigation into the hysteretic behavior of cold-formed austenitic stainless steel
square hollow section (SHS) brace members using a commercial finite element (FE) analysis software ABAQUS/Standard. The
initial/post buckling and fracture life of SHS brace members are comprehensively investigated through parametric studies with
FE models incorporating ductile fracture model, which is validated against the existing laboratory test results collected from the
literature. It is found that the current predictive models are applicable for the initial buckling strengths of SHS brace members
under cyclic loading, while result in significant inaccuracy in predictions for the post-buckling strength and fracture life. The
modified predictive model is therefore proposed and the applicability was then confirmed through excellent comparisons with
test results for cold-formed austenitic stainless SHS brace members.
