摘　　要：采用ECCS的计算模型和单元分析的计算模式 ,利用计算机程序 ,经过大量统计分析与计算 ,得到了钢管混凝土轴压构件抗火承载力的回归计算公式 ,并与国内外的结果对比 ,吻合较好 。A large amount of statistic calculation on the squash load of centrally loaded concrete filled steel tubular columns exposed to fire has been carried out through using the computer program, and the regression formulas are established. From the comparisons of results respectively obtained by the formulas and experiments, it is concluded that the formulas are applicable with reasonable accuracy for fire resistant design of concrete filled steel tubular columns.
