摘　　要：建筑物受火灾的影响很大,在火灾发生后,构件会出现裂缝、脱落、变形等情况,材料性能、承载能力会降低,甚至影响结构整体安全。为做好火灾后工程结构恢复重建、维修管理、工程事故处理等工作,需对火灾后的工程结构进行检测鉴定。文章以某高层住宅楼火灾后检测鉴定为例,通过现场调查了解、材料性能检测、材料微观分析等方法,综合评估火灾后结构构件的损伤程度、影响范围。研究表明:建筑物火灾后的检测鉴定,应先初步对结构构件等级进行评定,然后结合各种检测技术手段,综合对构件进行详细鉴定评级,给出火灾对构件的影响程度,以便于后续采取具有针对性的加固处理措施。The building is greatly affected by the fire,after the fire,the components will appear cracks,fall off,deformation,etc.,the material performance,bearing capacity will be reduced,and even affect the overall safety of the structure.In order to do well the reconstruction,maintenance and management of the engineering structure after the fire,it is necessary to test and appraise the engineering structure after the fire.Taking a high-rise residential building fire detection and identification as an example,this paper comprehensively evaluates the damage degree and influence range of structural components after fire through field investigation,material property detection and material microscopic analysis.The research shows that:In the detection and identification of buildings after fire,the grade of structural components should be initially assessed,and then the detailed identification and rating of components should be carried out in combination with various detection techniques to give the impact degree of fire on components,so as to facilitate the subsequent adoption of targeted reinforcement measures,in order to provide reference for the detection and identification of buildings after fire.
