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 existing foreign fire-resistant design methods in the technical standards of stainless steel structure and the related experimental research on stainless steel components that has been carried out, the fire resistant design methods of stainless steel are comprehensively analyzed. Differences in fire design methods. The analysis shows that the fire resistance design method of the European EN 1993-1-2 is the same as that of the stainless steel beam in the European “Stainless Steel Design Manual”, but the calculation result of the fire-resistant design method based on the test is low. The European EN 1993-1-2, European “stainless steel design manual” based on the experimental design of the fire-resistant stainless steel columns calculated results are similar.
