摘要
基于塑性极限分析理论,给出一种钢框架抗火计算方法.该方法可以计算出火灾条件下,钢框架塑性铰产生的条件、次序以及极限温度,钢框架的内力、位移,模拟钢框架破坏的全过程,可以基本确定钢框架的防火保护范围.
In this paper, based on plastic limit analysis theory a method for the calculation of fire resistance of steel structures is put forth. By this method, the sequence of plastic hinges and terminal temperature of steel frame under fire and its stress and strain are calculated. The whole collapse process of steel frame under fire is simulated, and the fire prevention scope of the steel frame is determined.
