| 摘 要： | 为了分析高温下钢材力学性能的变化对结构抗火性能的影响，对基于不同材性模型下的结构分析结果进行了比较，结果表明，结构抗火分析结果的精确性很大程度上依赖于所采用的高温下材料的应力－应变关系

| Abstract: | In order to analyse the effect of the change of the steel mechanic properties under high temperature on fire resistance of structures,comparision based on the structural analysis for different material property models is given herein.Results show that the accuracry of the analytical results for steel structures at high temperature depends largely on the high temperature stress-strain relations. |

| Keywords: | steel structure fire resistance analysis material property model stress-strain curves yielding point initial modules of elasticity |
