摘要：A three-dimensional non-linear finite element (FE)model for thin-waist concrete filled steel tubular (CFST) columns is established. The mechanical properties of thin-waist CFST short columns under axial compression are analyzed. The ultimate strength and the axial load-axial curves calculated by the FE model are in good agreement with the experimental results. The FE model presented in this paper can be used for reference in the non-linear analysis of CFST columns.
