张同亿,肖自强,李亮,张锐,罗斌,张建明(中国中元国际工程公司,北京 100089)[摘要]北京财富中心二期公寓楼结构高度194m,采用框架核心筒型钢混凝土混合结构体系。介绍了结构体系及布置、结构设计思路、抗震设防性能化目标、结构整体计算分析结果等。特别给出地基基础沉降分析、转换结构体系比选及转换块结构有限元分析、平面外伸部分子结构分析、外框承担剪力分析等专项分析内容及方法。最后探讨了混合结构在高烈度地区超高层建筑中的适用性及建议。[关键词]混合结构; 高层建筑; 结构分析; 转换结构中图分类号:TU318.2 文献标识码:A 文章编号:1002-848X(2013)03-0059-04Structural design on apartment tower of Fortune Center phaseⅡin BeijingZhang Tongyi, Xiao Ziqiang, Li Liang, Zhang Rui, Luo Bin, Zhang Jianming(China IPPR International Engineering Corporation, Beijing 100089, China)Abstract: The tall apartment building of Fortune Center phaseⅡ in Beijing is 194m height, and mixed frame-corewall structure is adopted. The structure system and arrangement, some structural design ideas, performance-base seismic objectives and structure calculation analysis results were provided. Some special analysis methods and contents were given such as foundation settlement analysis, transformation structure system election and finite element analysis on conversion block structure, overhang substructure analysis, out-frame shear force analysis, etc. Finally the applicability and suggestions were discussed for the application of tall mixed structure in high intensity area.Keywords: mixed structure; tall building; structural analysis; transformation structure作者简介:张同亿,博士,教授级高级工程师,Email: zhangtongyi@ippr.net参考文献[1]JGJ 3—2002 高层建筑混凝土结构技术规程[S]. 北京:中国建筑工业出版社,2002.[2]GB 50011—2001 建筑抗震设计规范[S]. 北京:中国建筑工业出版社,2001.[3]徐培福,薛彦涛,肖从真,等. 高层型钢混凝土框筒混合结构抗震性能试验研究[J].建筑结构, 2005,35(5):3-8.[4]徐培福,戴国莹.超限高层建筑结构基于性能抗震设计的研究[J]. 土木工程学报,2005,38(1):3-10.[5]黄吉锋,李云贵,邵弘,等.考虑弹塑性内力重分配的框剪结构等剪应力调整[J]. 建筑科学,2005,21(3):3-9.
