灾后混凝土受损性能分析与强度检测

Post-disaster performance analysis of damaged concrete and intensity detection

建筑物受火灾后,其材料和结构的性能都会发生巨大变化,从而降低构件和整个结构的承载能力。通过对受损后的混凝土强度性能进行分析,运用现场检测方法和试验,得出了混凝土受损后的强度损失值,从而为受火灾损伤的混凝土构件的处理和加固提供有用的参考。

The architecture＇ s materials and its structure performance would change a lot after fire so that the carry- ing capacity of the whole structure would be reduced. By carrying out the performance analysis of the intensity of damaged concrete, this paper reveals the loss of the reinforcing the fire -damaged concrete members intensity, aiming to provide an useful reference to handling and
