［摘要］曲靖金都佳园1栋塔楼建筑高度为218m，是集商业和公寓式酒店为一体的综合楼，采用带加强层的框架-核心筒结构体系。介绍了该工程结构选型、抗震性能设计目标以及主要分析结果。采用ANSYS软件进行特征值屈曲分析以确定型钢柱的计算长度系数，并按此计算长度系数进行型钢柱承载力分析。采用MIDAS/Gen软件进行施工阶段模拟分析和罕遇地震静力弹塑性分析，计算结果表明，考虑混凝土收缩徐变及实际施工顺序的影响比不考虑时构件的内力大，弹塑性层间位移角满足要求。该工程结构安全可靠，满足抗震性能设计目标。［关键词］曲靖金都佳园; 混合结构; 计算长度; 施工模拟; Pushover中图分类号：TU318 文献标识码：A 文章编号：1002-848X(2015)22-0007-06
Structural analysis of No.1 Building in Jindujiayuan in QujingLu Wei1, Li Yansheng1, Dong Jiang2, Wang Wenyuan1, Duan Erhuan1(1 Kunming Yingzao Engineering Design Co., Ltd., Kunming 650000, China; 2 Yunnan Antai Checking Center of Construction Project Shop Drawing Documents, Kunming 650000, China)Abstract: The No.1 Building in Jindujiayuan in Qujing, which has architecture height of 218 meters, is a comprehensive building with business and residence hotel inside as a whole. It adopts hybird structuaral system of frame-core wall with strengthened stories. The struactural system selection of the building was introduced as well as seismic performance design goals and the mian analysis results. The calculation coefficient of effective length of steel reinforced column was determined according to eigenvalue buckling analysis by ANSYS software, and it was used to analyze the bearing capacity of steel reinforced column. The simulation analysis of construction stage and Pushover analysis under the rare earthquake were carried out by MIDAS/Gen software. The results indicate that component internal forces are bigger when concrete shrinkage and creep as well as real construction consequence are considered, elastic plastic story drift angle meet the requirements. The structure of this project is secure and reliable, and it can fulfill seismic performence design goals.Keywords: Jindujiayuan in Qujing; hybrid structure; effective length; construction simulation; Pushover
