POST-FIRE DETECTION AND IDENTIFICATION OF A LARGE-SPACE MIXED-STRUCTURE BUILDING
Fire accidents frequently happen in public buildings.Buildings with complex mixed structures and large spaces are subjected to complicated and difficult work of detection and identification of detection and identification of post-fire.According to a case study,we discuss the principle of detection and identification,as well as the identifi-cation rating and the corresponding measures to be taken.We propose a working directory of preliminary investiga-tion,preliminary identification after fire,component investigation and detection in the fire-affected area,component investigation and detection outside the fire-affected area,detailed identification after fire,and overall safety apprais-al of the structure.The methods and special attentions should be paid to the testing of material properties after con-crete and steel structure fires.The research may provide the reference for ideas checking,detection methods,and monitoring content for subsequent identification work after fire accidents.
