［摘要］杭州博地世紀(jì)中心北塔樓結(jié)構(gòu)高度為276m，主體結(jié)構(gòu)采用鋼管混凝土框架柱+鋼筋混凝土核心筒結(jié)構(gòu)體系。結(jié)構(gòu)分析中合理考慮風(fēng)荷載，通過SATWE，MIDAS Building兩種軟件獨(dú)立建模以對(duì)比分析主體結(jié)構(gòu)彈性階段的結(jié)構(gòu)特性，同時(shí)提出結(jié)構(gòu)的抗震性能目標(biāo)。通過動(dòng)力彈塑性時(shí)程分析驗(yàn)證結(jié)構(gòu)在罕遇地震作用下的抗倒塌能力，最后提出本工程復(fù)雜超限結(jié)構(gòu)設(shè)計(jì)的主要加強(qiáng)措施。

Abstract:The north tower of Hangzhou Bodi Century Center with the structural height of 276m adopts structural system of steel tube concrete frame column and reinforced concrete corewall. In the structure analysis, wind load was reasonably considered. The structural features of the main structure in elastic period were compared and analyzed with two independent models by programs of SATWE and MIDAS Building. Meanwhile, the seismic performance targets of the structure were also presented. The collapse capability under the rare earthquake was validated by dynamic elasticplastic timehistory analysis. At last, specific strengthening measure on this complicated outofcode structural design were proposed.

Keywords:outofcode highrise building; hybrid structure; elasticplastic analysis; inclined shearwall
