以深圳地区某超高层建筑为工程案例,对其在不同地震作用下的抗震性能进行分析。采用了ETABS软件分析该结构在多遇地震作用下的性能,使其满足规范要求。运用STRAT软件进行结构大震弹塑性分析,并对关键构件的损伤状态进行研究。分析结果表明结构在多遇地震和罕遇地震下都达到了性能设计的目标,满足“小震不坏、中震可修、大震不倒”的设计目标,抗震性能达到相关规范标准。
Taking a super high-rise building in Shenzhen as an engineering case, its seismic performance under different earthquakes was analyzed. The ETABS software was used to analyze the performance of the structure under multiple earthquakes to meet the specifications. The STRAT software was used to analyze the elasto-plasticity of large-scale structural earthquakes and the damage status of key components was studied. The analysis results show that the structure has reached the goal of performance design in the case of multiple earthquakes and rare earthquakes, and meets the design goals of “small earthquakes are not bad, moderate earthquakes can be repaired, large earthquakes do not fall down”, and the seismic performance reaches the relevant specification standards. .
