混凝土“火灾温度”鉴定方法研究

Method for identifying "conflagration temperature" of concrete

据统计,建筑火灾主要发生于公共建筑、多层住宅、厂房等场所,这些场所的结构类型多为混凝土结构,而这些结构在承重构件处大都采用的是混凝土材料,因此当建筑物遭受火灾后,须通过鉴定确认承重构件混凝土材料的受害情况和损坏程度,过火后混凝土材料在鉴定中,"火灾温度"对材料的性能影响极大。对混凝土"火灾温度"的鉴定方法进行分析,为结构的加固修复方案提供科学依据。

According to the statistics, architectural conflagrations usually break out in public buildings, multi-layered housing and factory buildings,whose structure type is mainly concrete structure,whose load-bearing components are often made of concrete material.Therefore after the building is hit by conflagration,the loss situation and the degree of damage in the load-bearing components must be identified.The property of such material is found to be greatly affected by the ＂conflagration temperature＂.This study aims at analysing the method for identifying ＂conflagration temperature＂, so as to offer scientific support for the plan of reinforcing and restoring the damaged structure.
