| 摘 要： | 上海某北塔楼是带加强层巨型柱核心筒的超高层结构，并存在加强层及伸臂桁架的钢-混凝土组合结构。本文中应用的静力弹塑性分析采用中国建筑科学研究院的程序PKPM系列PUSH进行。该程序是一个三维有限元空间弹塑性静力分析程序，利用PKPM的PUSH建立了上海某北塔楼的三维非线性有限元模型，并进行推覆分析，得到结构的层间位移和层间位移角，找出了结构的薄弱部位，分析了构件的屈服和破坏规律，对同类工程的分析有较高的参考价值。 |

| Abstract： | A north tower in Shanghai is a super high-rise structure with strengthened stories, giant column and core tube,which with strengthened stories and cantilevered truss steel-concrete composite structure. Push-over analysis was applied using the program PKPM series PUSH of Chinese Academy of Building Research in this paper. The program is a three-dimensional finite element space-plastic static analysis program. Using PUSH of PKPM, the three-dimensional non-linear finite element model of the north tower in Shanghai was established and the push-over analysis was carried out. The inter-story displacement of the structure and the angle of it were obtained, the weak parts of the structure were found out, and the yield and destruction law of the components was analyzed. These have a high reference value for the analysis of the similar project. |
