摘要：

Concrete-filled stainless steel tube (CFSST) has great potential to be applied in the marine environment attributed to its excellent structural behavior and corrosion resistance. This paper presents numerical investigation and parametric study on the performance of CFSST members subjected to concentric tension. Firstly, a three dimensional finite element analysis (FEA) model is established and validated against the experimental results reported in a companion paper. Secondly, the calibrated FEA model is used to investigate the tensile behavior of CFSST members, especially the composite action and stress distribution between the outer stainless steel tube and the concrete infill, which determines the load-carrying capacity of the steel–concrete composite member. Then, a wide-range parametric analysis is conducted by varying the parameters of both the stainless steel tube and concrete infill, and the influence of different parameters on the load-carrying capacity of CFSST tensile members is studied. Finally, a calculation model is proposed to be used to predict the ultimate strength of CFSST tensile members, and a good agreement is achieved between the model-predicted values and the FEA-computed ones.
