摘要
采用有限元方法,对门式刚架梁连接节点在局部火灾作用下的温度分布进行了数值模拟分析,得到温度场分布云图及其分布规律,并与试验结果进行对比分析,为基于局部火灾下钢构件的温度场分布提供有效的有限元模拟方法.
The temperature of joints of a certain variable cross-section portal rigid frame under local fire was simulated using finite element method. The corresponding contour maps and laws of the temperature field were obtained and compared with testing data. As a result, an effective finite element method to steel structure temperature under local fire was set up.
