深圳迈瑞大厦为超A级高度的超限高层建筑。采用基于性能的抗震设计方法对该结构抗震设计的可行性进行了研究。根据本工程采用的结构体系、平面布置和结构高度超限特点,选用了适合本工程的抗震性能目标。通过采用SATWE和ETABS程序进行小震作用下计算结果对比分析、中震作用下构件不屈服判别分析、大震作用下静力推覆(push-over)分析,找到了结构的抗震薄弱环节,采取了相应的抗震加强措施。研究结果表明,工程结构抗震设计及采取的抗震加强措施能满足“小震不坏、中震可修、大震不倒”的抗震设防要求。
Mindray Building, Shenzhen is a super A-level high-rise buildings. The feasibility of the seismic design of the structure is studied by the performance-based seismic design method. According to the structural system, plane layout and structural height overrun characteristics adopted in the project, the seismic performance targets suitable for the project are selected. Through comparative analysis of the calculated results under the action of small earthquakes using SATWE and ETABS programs, the member does not yield discriminant analysis under medium earthquakes and the push-over analysis under large earthquakes finds the weak points of the structure’s seismic resistance, The corresponding seismic strengthening measures. The results show that the seismic design of the structure and the seismic strengthening measures taken by the project can meet the seismic requirements of “small earthquake is not bad, moderate earthquake repairable, large earthquake does not fall”.
