摘要]杭州西子國(guó)際項(xiàng)目為杭州市城市綜合體項(xiàng)目,其中三棟主樓均由兩棟不等高塔樓錯(cuò)合連體而成,呈L形。其獨(dú)特的連體造型及復(fù)雜的功能導(dǎo)致結(jié)構(gòu)多項(xiàng)規(guī)則性指標(biāo)超限。采用基于性能的抗震設(shè)計(jì)方法,對(duì)結(jié)構(gòu)進(jìn)行了小震彈性、中震彈性和中震不屈服驗(yàn)算,以及大震下的彈塑性分析。并提出相應(yīng)的結(jié)構(gòu)抗震措施,保證結(jié)構(gòu)能夠?qū)崿F(xiàn)預(yù)期的抗震性能目標(biāo)。

Abstract:Hangzhou Xizi International Project is an urban complex project in Hangzhou. All of three main buildings are L-shaped buildings that consist of two connected towers with different-height. The complex function and special shape of the towers lead the structural regularity indexes to be out-of-code, so performance-based seismic design method was adopted. Performances of the structure were verified based on bearing capacity and deformation under different levels, including elastic analysis under frequent earthquake, unyielding and elastic analysis under intermediate earthquake, and elastic-plastic analysis under rare earthquake. Series of structural measures were suggested to accomplish the expected seismic performance objectives.

Keywords:out-of-code high-rise building; complicated connected structure; performance-based seismic design; elastic-plastic analysis
