钢结构暨空间结构的抗火设计综述

Review on Fire-Resistant Design of Steel and Space Structure

钢结构暨空间结构是目前建筑结构的重要发展方向之一。因钢材对高温的敏感性 ,其防火、抗火性能的研究应是设计时考虑的重要因素。笔者简述了抗火与防火的概念及其区别 ;评估了国内外关于抗火设计的基本方法及优缺点 ;重点对整体结构有限元非线性抗火反应全过程分析方法进行了讨论。通过选择科学的抗火设计方法 ,将为经济。

Steel and space structures are the most important and promising aspects of structure in China. Due to the high temperature sensibility of steels, characteristics of fire prevention and fire resistant of the structure should be considered as an important factor in design. The concepts of and the differentiation between fire prevention and fire resistant are discussed. The basic methods for fire resistant design used both at home and abroad, and their comparative merits and defects are introduced. The entire structure non linear finite element fire resistant response method in an overall process analysis is emphatically discussed. To select a reasonable fire resistant method is the basis of an economical and practical fire prevention design.
