摘要: 杭州中心的地上双塔采用框架-核心筒结构，裙房采用框架-剪力墙结构。杭州中心设计的主要难点是紧邻地铁的超深地下室、复杂大底盘双塔结构。从基础设计、支护结构设计、地下室设计关键问题等方面阐述了此类超深地下室设计要点及难点。介绍了上部结构的结构体系、主要不规则项、抗震性能化设计等内容。采用 YJK 软件重点研究了高层大底盘裙房对双塔结构的影响。最后，通过 PKPM-SAUSAGE 软件对结构进行动力弹塑性时程分析，结果表明地上结构可满足既定的性能化设计目标。

Abstract: The above-ground twin towers of Hangzhou Center adopt a frame-core tube structure,and the podium adopts aframe-shear wall structure. The main difficulty in the design of Hangzhou Center is the ultra-deep basement adjacent to thesubway and the complex double-tower structure with large chassis. The key points and difficulties of such ultra-deepbasement design were expounded from the aspects of foundation design,support structure design,and key issues ofbasement design. The structural system,main irregular items,and seismic performance-based design of the superstructurewere introduced. The influence of high-rise large chassis podium on twin-tower structure was mainly studied by using YJKsoftware. Finally,the dynamic elastic-plastic time history analysis was carried out by PKPM-SAUSAGE software,and theresults show that the above-ground structure can meet the established performance-based design goals.

Keywords:Hangzhou Center； ultra-deep basement； large cantilevered structure； super high-rise structure； dynamicelastic-plastic time history analysis
