火灾下钢筋混凝土框架结构的全过程分析

摘要

According to the simulation of the reinforced concrete frame structure in fire environment,the paper analyzes the change process of the temperature field in the frame structure,undertakes the whole-process analysis of the mechanical performance of the frame structure in the fire,and realizes the whole-process analysis of the fire response of the frame structure,so as to provide the theoretic reference for the fire-resistance design of the frame.%通过对钢筋混凝土框架结构火灾环境模拟,分析了框架结构内部的温度场变化过程,并对火灾下框架结构的力学性能进行了全过程分析,真正实现了框架结构火灾反应的全过程分析,为框架的抗火设计提供理论依据。
