The constraint steel column and beam in an experi-ment were simulated with ABAQUS which is the universal fi-nite element analysis software. The temperature measured by thermocouple wa9 used as initial load to carry out heat transfer analysis, obtaining the distribution of the whole constraint steel column and beam. Then the temperature distribution was taken as the initial conditions for carrying out coupled thermal-me-chanical analysis. Through comparing the variation of displace-rnment with temperature which was calculated by the universal fi-nite element analysis software and experimental results, the re-liability and the rationality using ABAQUS to carry out coupled thermal-mechanical analysis of steel components was verified.%采用通用有限元分析软件ABAQUS对某试验工况中的约束钢柱和钢梁进行模拟计算,将试验测得的热电偶温度数据作为初始荷载进行热传导分析,得到整个约束钢柱和约束梁的温度场分布,并以此为输入温度场进行热力分析.通过将有限元分析软件计算所得的位移随温度变化关系同试验数据比较,验证了利用ABAQUS进行钢构件热力耦合分析的工具可靠,方法合理.
