摘　　要：基于国外现有关于不锈钢结构技术标准中的抗火设计方法,并结合已开展的相关不锈钢构件相关试验研究,对不锈钢抗火设计方法进行较为全面的剖析,通过算例分析,给出各种抗火设计方法的差异性。分析表明:欧洲EN 1993-1-2与欧洲《不锈钢设计手册》中不锈钢梁的抗火设计方法基本相同,但基于试验的抗火设计方法计算结果偏低。而欧洲EN 1993-1-2、欧洲《不锈钢设计手册》与基于试验中不锈钢柱的抗火设计方法计算结果相近。Based on the fire resistance design methods in the existing code and relevant experiment research on stainless steel members at elevated temperature,a comprehensive analysis was performed on fire resistance design methods of stainless steel structures. Based on calculation examples,the difference among of the fire resistance design methods was given. The analysis showed that the fire resistance design methods for stainless steel beam in EN 1993-1- 2 and Design Manual for Structural Stainless Steel were basically the same,which were larger than the calculated results of experiment. Each fire resistance design method had similar calculation result for stainless steel column.
