| 摘 要： | 文章以整体结构为对象,以有限元分析软件ANSYS为平台,采用基于计算的结构抗火设计方法,本文通过对空间钢框架的温度-结构耦合计算,进行火灾情况下钢结构全过程反应分析,判断出火灾下结构的薄弱部位,考察受火构件与非受火构件的相互影响,更加真实地反映出结构的抗火性能。并给出了钢梁抗火的概念设计的建议。

| Abstract: | Taking whole structure as the object,on the basis of ANSYS,using structure fire-resistance design method that based on the computation.And through thermal-structural coupled calculation of the spatial steel frame,carry on entire process response analysis of the steel structure in the fire situation,have judged weak link of the structure under the fire,inspected the fire component with non-the fire component mutual influence,really reflect the fire-resistant performance of the structure.Some conceptual desig... |
