摘要
以某钢筋混凝土结构车库为研究对象,利用有限元分析软件COMSOL Multiphysic模拟计算火灾条件下混凝土结构的内部温度场和应力应变变化。结果表明,该方法可以有效地评估火灾后混凝土的损伤情况。
Taking a reinforced concrete garage as study object, COMSOL Multiphysic finite element analysis was used to simulate the inner temperature field and stress and strain of concrete structure after fire. The results showed that COMSOL Multiphysie is a effective way to assess damage of concrete.
