火灾后钢筋混凝土结构抗震性能分析

Anti-earthquake performance of RC frame after fire

钢筋混凝土结构在火灾的作用下 ,混凝土与钢筋的力学性能会发生变化 ,进而导致钢筋混凝土柱、梁、楼板和墙受到损伤。分析了火灾后各导致构件承载力降低的主要因素 。

The bearing capacity of concrete and steel will be changed under the effect of fire,thus RC column, beam, floor and wall will be damaged. The main factors, which can reduce the bearing capacity of components, are analyzed, the method to judge and inspect the components after fire are put forward.
