Behaviour of short and slender concrete-filled stainless steel tubular columns
Abstract In this paper, a series of tests were carried out on short and slender concrete-filled stainless steel tubular columns to explore their performance under axial compression or combined actions of axial force and bending moment. Empty short steel hollow sections were also tested for comparison. The test results showed that the performance of the composite columns was quite good and have the potential to be used extensively as structural members. Comparisons of the test results were also made with several existing design methods for conventional concrete-filled carbon steel tubular columns as presented in Australian standard AS 5100 (2004), American code AISC (2005), Chinese code DBJ/T 13-51-2010 (2010), and Eurocode 4 (2004), which indicates that all the codes are somewhat conservative in predicting the load-carrying capacities of both short and slender columns.
Research highlights ► Stainless steel composite columns show more ductile behaviour. ► Stainless steel composite columns have much higher residual strength. ► Current design codes underestimate the strength of stainless steel composite columns. ► More accurate design approach is needed to better utilise stainless steel.
