［摘要］蘇州月亮灣B3地塊建屋廣場E座建筑高度為222-80m，采用型鋼混凝土框架-核心筒結構體系，超B級高度，平面呈矩形，核心筒高寬比達22-27。設計中進行了腰桁架使用與否的多方案比較分析，結果表明不采用腰桁架方案較優(yōu)；針對核心筒高寬比過大的特點，結合抗震規(guī)范對本工程進行性能化設計；并采用SAUSAGE與ABAQUS兩種軟件對結構進行大震動力彈塑性時程分析，針對薄弱部位采取加強措施，確保結構具有較好的抗震和抗風性能。

Abstract:The building E in B3 block of Suzhou Moon Bay Building Plaza has building height of 222-80m, which adopts reinforced concrete frame-core tube structure system. The building E is an over B-level height building with rectangular plane, and the core tube aspect ratio of which is 22-27. In the design, the comparison and analysis of the schemes with or without waist trusses were carried, and the result show that the scheme without waist trusses is better. According to the characteristics of high aspect ratio of core tube, the performance-based design of this project was carried out combined with seismic code. The dynamic elastic-plastic time history analysis of the structure under the rare earthquake was also carried out with two kinds of software (SAUSAGE and ABAQUS), and strengthening measures were taken to the weak parts of the structure for ensure that the building has better performance under earthquake and wind.
Keywords:over B-level height; core tube aspect ratio; waist truss; performance-based design of seismic; dynamic elastic-plastic time history
