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。
After the fire of Jinan Olympic Sports Center Gymnasium, the main steel structure was tested by on-site rebound and steel microstructure analysis. Meanwhile, the deformation of reticulated shell was measured, and the internal force of member was supplemented with the monitoring data and the calculation of internal force of structure and analyse. The test results, deformation measurement results, component internal force monitoring data and theoretical calculation and analysis results were compared to analyze the safety of the fire after the structure to make the right appraisal.
