【 摘 要 】

The aim of this paper is to numerically investigate the behavior of the rectangular concrete filled stainless steel tubular (CFSST) columns subjected to bi-axial eccentric compression. A finite element (FE) model for modelling the bi-axial eccentric compressive behaviour was established. The FE predictions were verified against the test results. Behaviour analysis was then performed to investigate the typical curves of load versus deformation, the internal force distribution, stress development and interaction of stainless steel tube and core concrete during the loading process.
