商要】介绍了上海某幢超限高层住宅结构的抗震设计与分析。主楼地下3层,地上46层、高150m,设计采用钢筋混额土框架。[摘
剪力墙结构,使用了PKPM和Etabs进行整体结构在小震作用下的弹性时程分析和军遇地震作用下的静力弹型性分析,采用EPDA 进行弹塑性动力分析,各项计算指标均达到了规范的要求,结构设计和分析方法可供今后类似超限高层建筑和其他复杂结构设计参考。
[Abstract]This paper presents the seismic design andanalysis ofahigh-rise residence structure in Shanghai. The main building consistingof3 stories underground and 46stories overground, and total height is 150 meters. Thestructuralsystem is a frameshearwall with reinforced concrete PKPM and Etabs were used to do the linear time history analysis under frequent earthquake and static elastic-plastic analysis under rare earthquake. On the otherhand,the elastic dymamictime-history analysis under frequent earthquake and the static elastoplastic analysis under rare earthquake werealso calculated. Alltheseresults meetthedesign specifications basically. The design and analysis method introduced inthispaper
