摘　　要：蜀山南停车场项目·15 F小高层建筑高度为61.8 m,裙房2层顶面标高17.5 m,裙房以上15层,共17层,抗震设防烈度为6度,采用全框支剪力墙结构体系,转换形式为梁式转换,剪力墙在转换层进行转换,风压放大系数为1.1,体型系数为1.32。同时,本项目超过现行规范的适用范围,属于A级高层建筑,且存在多项不规则项。对此,文中对工程结构主要构件抗震性能目标进行分析,阐述了结构加强措施,并应用YJK软件对抗震性能水准1、性能水准2、性能水准3、性能水准4进行计算分析,为类似结构超限建筑结构设计提供借鉴与参考。The height of the 15F small high-rise building of the Shushan South Parking Lot Project is 61.8 m,the elevation of the top surface of the 2nd floor of the podium is 17.5 m,the 15 floors above the podium,a total of 17 floors,the seismic fortification intensity is 6 degrees,the structural system of the full-frame support shear wall is adopted,the conversion form is beam conversion,the shear wall is converted in the conversion layer,the wind pressure amplification coefficient is 1.1,and the body shape coefficient is 1.32.At the same time,the project exceeds the scope of application of the current code,belongs to the A-story building,and there are a number of irregularities.In this paper,the seismic performance objectives of the main components of the engineering structure are analyzed,the structural strengthening measures are expounded,and the seismic performance level 1,performance level 2,performance level 3 and performance level 4 of YJK software are used to calculate and analyze.This paper provides reference for the design of similar structures and overrun buildings.
