摘要
通过一起钢网壳火灾实例,从火场温度的判定、火灾后钢材性能分析、火灾后网壳承载能力分析等几方面对球面网壳结构在遭遇火灾后的鉴定方法和剩余承载能力进行了探讨,并提出了加固修复方法,从而提高网壳结构的耐火性能。
Through the fire of the steel reticulated shell, the paper discusses the identification method and the residual loading capacity of the spherical lattice shell after the fire from the aspects of the decision of the temperature on the fire scene, the analysis of the steel performance after the fire and the analysis of the loading capacity of the reticulated shell after the fire, and puts forward the method of the reinforcement and repair to improve the fire resistance performance of the lattice shell structure.
