摘要	In order to simulate the real fire attack, this paper presents a finite element model (FEM) of concrete-filled steel tubular (CFST) columns after exposure to overall stage of fire with sustained axial load based on ABAQUS. The whole phases including loading at ambient, heating, cooling and post-fire, which followed the ISO-834 standard fire curve. The reasonable thermal and material models were used in the FEM. The mechanical behavior of CFST columns working in entire stage of fire was discussed included axial load and bend. It is shown that the results of bearing capacity which considered cooling stage will higher than natural cooling due to the effective recovery of steel. The results of this paper can provide a basis for fire-damage assessment of CFST columns.
