摘　　要：大空间钢结构由于结构体系复杂,建筑使用或造型上的需要常常造成很难根据我国现行的建筑防火类规范进行防火设计,有必要对科学性、安全性均较高的防火性能化设计方法进行系统的研究。对国内外性能化设计方法的发展情况进行了总结,并对我国几个采用此方法进行防火设计的工程进行了对比分析,还对温度场分布以及整体力学性能的计算方法进行了研究与讨论。希望能够为相关领域的工程设计人员提供一定的参考借鉴作用。Traditional fire-resisting method in codes and regulations in China can not be applied to large spatial structures as the structural systems are mostly sophisticated or sometimes there are special aesthetic demands on the structures. It’s necessary to conduct comprehensive investigations on fire-resisting performance-based design method with higher scientific and safety level. The development of this method in China and overseas is summarized, and successful practices adopting this method in China were also employed to make comparative analysis. Calculation approaches for temperature distribution and global mechanical performance are then discussed deeply. Suggestions are made to give references for civil engineers.
