ABSTRACT:

Steel-concrete composite members are used extensively in structures as economic load-carrying components. An emerging topic in the field of composite construction is the use of stainless steel considering its higher durability, corrosion resistance, and fire resistance as well as its aesthetic benefits and ease of maintenance compared to traditional carbon steel. Consequently, the present study investigates the stability of the outer tube in concrete-filled stainless steel tubular (CFSST) columns through detailed numerical simulations. After verification of the developed finite element model through comparison with independent experimental results, the local and post-local buckling behaviours are investigated in a wide range of square and circular CFSST columns. Results are thoroughly discussed through comparison with theory as well as approaches in use by international design standards. The simulation results are finally synthesised to recommend yield slenderness limits as well as effective width formulae for CFSST columns.
