摘要
应用大型通用有限元程序ANSYS对钢管混凝土在火灾条件下的温度场进行模拟计算,提供了一种精确分析火荷载条件下钢管混凝土内部温度分布的研究方法.通过与有关火灾实验分析比较,证明方法概念正确,分析过程简便,计算精度可靠,可以为钢管混凝土的耐火极限确定提供有效的数据.
In this paper, the simulating analysis of concrete filled steel tube in fire disaster is performed using ANSYS, the commercial FE program is widely used around the world. A precise analysis method is presented to perfectly analyze the distribution of the internal temperature of steel columns filled with concrete in fire disaster. According to the comparison among the experiments of fire disaster, the conception is correct; the processes are simple, and the calculations are precise.
