| 摘 要： | 对一个单层单跨钢框架结构进行抗火反应分析,运用大型有限元分析软件ANSYS中的三维热力耦合单元对该结构进行温度计算和力学分析,研究了火灾下结构的薄弱环节,得到结构的耐火时间和临界温度,并得出了各个时刻结构的温度场和变形,从而更加真实地反映出平面钢框架结构的抗火性能。

| Abstract: | Anti-fire reaction analysis on a single-story and single-bay steel framework structure,using three dimensional thermal coupled unit of large finite element analysis software ANSYS for temperature calculation and mechanical analysis,research into its weaknesses under fire hazard,all this leads to the structure’s the refractory time and the critical temperature,the temperature field and deformation,which more faithfully reflect the fire resistance properties of steel frames. |
