摘要
采用非线性有限元方法对火灾时混凝土构件的温度场进行了仿真计算,计算结果与试验数据吻合较好,在此基础上计算了多种火灾情况下混凝土受压柱的温度分布情况,为灾后建筑物的检测评定与加固设计提供了一定的依据。
In this paper, the temperature field of concrete specimen under fire is calculated by means of nonlinear finite element method. The calculated results correspond with test data. On the basis of above analysis, temperature distribution of compressed concrete column under variety fire is calculated, which provides credible reference for detection valuation and reinforcement design of buildings after fire.
