摘　　要：分析了高温状态下的钢管混凝土柱耐火性能,提出了轴压钢管混凝土柱的耐火极限理论计算方法,将其计算结果与轴压试验结果进行对比分析,结果表明:理论计算公式与试验结果吻合较好,为进一步分析钢管混凝土柱的耐火性能奠定了理论基础。Analysis of the fire resistance of steel hollow columns filled with concrete under high temperature is made. The calculation of the fire resistance limit of steel hollow columns filled with concrete under axial force in high temperature is put forward. And comparing the calculation result with the axial force experimental result, it shows the theoretical calculation result is the same with the experimental result, which prorides a theoretical basis to further analysis the fire resistance of steel hollow columns filled with concrete.
