英文摘要	In order to study the fire resistance of concrete-filled circular steel tubular columns subjected to post-earthquake fire, reasonable seismic damage index and material constitutive model were selected. The finite element (FE) model of concrete-filled steel tubular columns under cyclic loading and fire was developed by finite analysis software ABAQUS. The FE model was verified with corresponding experimental tests. On this foundation, using data transfer function in ABAQUS, the finite element model for fire resistance of concrete-filled circular steel tubular columns after earthquake was established. Taking the typical axial compression member of circular concrete-filled steel tubular column as analysis object, the failure mode and damage mechanism of member subjected to post-earthquake fire were analyzed. The influence of damage index on the fire resistance of concrete filled circular steel tubular columns was studied. The results shown that the failure mode of concrete-filled circular steel tubular column under high temperature is developed and spread on the basis of the early earthquake damage. Damage index is an important parameter affecting the fire resistance of the concrete-filled steel tubular column subjected to post-earthquake fire. With the increase of damage index, the fire resistance of concrete filled circular steel tubular columns decreases. © 2017, Editorial Office of Journal of Building Structures. All right reserved.
