摘要
指出了现行规范在实际应用中的不足 ,提出了钢结构性能化抗火设计方法的基本框架。讨论了钢结构抗火设计的总体目标、功能目标和性能要求。该方法可充分考虑不同业主及不同建筑结构抗火设计的不同要求 ,同时确保火灾发生后建筑物内人员的安全及结构抗火设计的最优综合经济指标。并探讨了钢结构性能化抗火设计需解决的关键问题。
The disadvantages of the current codes in practice on fire-resistant design of steel structures are indicated, and a preliminary scheme for performance-based fire-resistant design of steel structures is proposed. The general aim, functional aim and the required performance of fire resistance of steel structures are introduced, which can satisfy different owners of different buildings. The key problems on the performance-based fire-resistant design of steel structures are discussed.(
