摘要: 杭州中心的地上雙塔采用框架-核心筒結(jié)構(gòu)，裙房采用框架-剪力墻結(jié)構(gòu)。杭州中心設(shè)計(jì)的主要難點(diǎn)是緊鄰地鐵的超深地下室、復(fù)雜大底盤雙塔結(jié)構(gòu)。從基礎(chǔ)設(shè)計(jì)、支護(hù)結(jié)構(gòu)設(shè)計(jì)、地下室設(shè)計(jì)關(guān)鍵問(wèn)題等方面闡述了此類超深地下室設(shè)計(jì)要點(diǎn)及難點(diǎn)。介紹了上部結(jié)構(gòu)的結(jié)構(gòu)體系、主要不規(guī)則項(xiàng)、抗震性能化設(shè)計(jì)等內(nèi)容。采用 YJK 軟件重點(diǎn)研究了高層大底盤裙房對(duì)雙塔結(jié)構(gòu)的影響。最后，通過(guò) PKPM-SAUSAGE 軟件對(duì)結(jié)構(gòu)進(jìn)行動(dòng)力彈塑性時(shí)程分析，結(jié)果表明地上結(jié)構(gòu)可滿足既定的性能化設(shè)計(jì)目標(biāo)。

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
