英文摘要	Concrete-filled steel tubular members with internal profiled steel have prosperous development in practical engineering duo to the high bearing capacity and good ductility and energy dissipation. This paper presents a finite element (FE) model of concrete-filled steel tubular column (CFST) with internal profiled steel to study the full-range fire performance under eccentric compression using the ABAQUS software based on the reasonable material models of steel and concrete. The axial load versus displacement curves were calculated and stress and strain distribution were analyzed when exposed to full-range fire. Parametric studies of CFST members with internal profiled steel were also performed. The results show that the fire load ratio of column, ascending time ratio, slenderness ratio of column and the steel ratio of tube have significant effects on the bearing capacity. ©, 2015, Tsinghua University.
