摘　　要：某会展中心为钢管混凝土柱承式空间桁架结构,属于人员高度密集的公共建筑。自天津8.12爆炸后部分建筑结构构件受损,采取临时加固措施后至今未使用。论文基于对该建筑现场检查检测和承载力验算结果,对会展中心进行安全性及抗震鉴定,并考虑爆炸荷载作用,对结构进行受力分析。基于鉴定分析结论并综合考虑经济因素和实施条件,给出后续处理建议。本文的检测鉴定技术方法对解决同类工程问题提供了较为全面的参考依据。A convention and Exhibition Center is a concrete-filled steel tubular column through space truss structure,which belongs to a highly crowded public building.Since the August 12 explosion in Tianjin,some building structural components have been damaged and have not been used since temporary reinforcement measures were taken.Based on the results of on-site inspection and bearing capacity checking of the building,this paper evaluates the safety and seismic performance of the Convention and Exhibition Center,and analyzes the stress of the structure considering the effect of explosion load.Based on the appraisal analysis conclusion and comprehensively considering the economic factors and implementation conditions,the follow-up treatment suggestions are given.The detection and identification technology and methods in this paper provide a more comprehensive reference basis for solving similar engineering problems.
