摘要：

Crisscross concrete-filled steel tube core column is a kind of new component. In this paper, the cross-sectional temperature distributions and thermal-stress of crisscross concrete-filled steel tube core columns are analyzed by using nonlinear finite element method under eight-side fire, so we can acquire mechanics performance in the high temperature life and fire-resistant. Simulation results show that: this kind of construction has a good inherent performance under fire, moreover, reducing load is an effective measure to improve the fire resistance of crisscross concrete-filled steel tube core columns.
