［摘要］杭州博地世纪中心北塔楼结构高度为276m，主体结构采用钢管混凝土框架柱+钢筋混凝土核心筒结构体系。结构分析中合理考虑风荷载，通过SATWE，MIDAS Building两种软件独立建模以对比分析主体结构弹性阶段的结构特性，同时提出结构的抗震性能目标。通过动力弹塑性时程分析验证结构在罕遇地震作用下的抗倒塌能力，最后提出本工程复杂超限结构设计的主要加强措施。

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
