（同济大学建筑设计研究院（集团）有限公司，上海 200092）［摘要］东吴文化中心2#楼为采用钢筋混凝土框架-剪力墙结构的超限多层建筑，由于结构分塔、连体情况复杂，楼板不连续，使得结构多项平面、立面不规则，造成结构超限。通过调整结构整体刚度、提高关键构件抗震性能目标，并进行抗震性能化设计和静力弹塑性分析以及适当的构造措施，解决了结构超限、大开洞、超长、大跨桁架等难题，使得结构满足抗震设防要求。［关键词］超限多层建筑; 超长结构; 抗震性能化设计中图分类号：TU318.2 文献标识码：A 文章编号：1002-848X(2014)22-0021-04Structural analysis and design of Dongwu Culture Center No.2 buildingZheng Hongzhi(Tongji Architectural Design (Group) Co., Ltd., Shanghai 200092, China)Abstract: Dongwu Culture Center No.2 building is a out-of-code multi-story RC frame-shearwall building. The structure has irregularities in plan and elevation due to multi-towers, connectingbody and discontinuous floors. The structural overall rigidity was adjusted and performancebased seismic design objectives of key components were developed. Meanwhile, Pushover analysis on overall structure was carried out for suitable seismic design details. The challenges of out-of-code items, large opening, super-long structure and large-span truss were solved to make the overall structure fulfill relevant seismic precautionary requirements.Keywords: out-of-code multi-story building; super-long structure; performance-based seismic design作者简介：郑鸿志，博士，工程师，Email:zheng_hongzhi@sina.com。参考文献［1］GB 50011—2010 建筑抗震设计规范［S］. 北京：中国建筑工业出版社，2010.［2］江苏省房屋建筑工程抗震设防审查细则［S］. 南京：江苏省建设厅，2007.［3］JGJ 3—2010 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，2011.［4］GB 50009—2012 建筑结构荷载规范［S］. 北京：中国建筑工业出版社，2012.
