摘要
济南奥体中心体育馆火灾后,对主体钢结构采用了对比硬度回弹和钢材金相组织分析的方法进行现场检测,同时对网壳变形进行测量,对构件内力补充监测数据,并进行结构内力计算与分析。将检测结果、变形测量结果、构件内力监测数据与理论计算分析结果进行比较分析,对火灾后结构的安全性做出正确的鉴定评价。
Rebound hardness comparision and steel microstructure analysis method on field have been used on the inspection of the main steel structure of Jinan Olympic Sports Centre Stadium.Simultaneously,the deformation of the reticulated shell was measured,the inspection data of the internal force in members were complemented,and the structural intenal forces have been calculated and analyzed.Results of inspection and measurement were compared with the theoretical analyzed calculation results.The structural safety c...
