摘　　要：火灾是影响钢结构设计的最主要因素。对钢结构抗火设计的现行方法进行了分析,并指出各种方法所存在的缺陷,通过对钢结构抗火力学性能的研究,参照欧洲标准对常见钢材高温下应力-应变性能进行了分析与计算,得出了便于使用的应力-应变关系。Fire is one of the main factors affecting the steel structure design. This paper analyzes the general study of fireresistant steel structure designs and points out the flaws for various methods. Through the fire resistance performance study of steel structures, in the light of the common European standards, the mechanical properties of steel under high temperature have been analyzed and calculated and the more practical stress-strain relationship has been obtained.

关 键 词：钢结构 抗火 应力-应变曲线
