摘　　要：本文给出钢框架结构的抗火极限状态定义,基于结构温度内力和钢框架非线性静力反应分析,提出一种钢框架结构抗火极限状态的实用分析方法,可直接用于钢框架结构的抗火设计.In this paper the limit state of steel framed structures against fire is first defined.Then based on the analysis of internal forces induced by' temperature variation and the analysis of nonlinear static response of steel frames, a practical method for limit state analysis of steel framed structures is proposed,which can be directly applied to the fire resistant design of steel framed structures.

关 键 词：火灾 钢结构 框架 极限状态
