(北京市建筑设计研究院有限公司， 北京 100045)［摘要］北京市凯特大厦主塔楼为混合结构，由钢筋混凝土核心筒、型钢混凝土柱、型钢混凝土梁组成，楼板为组合楼盖体系（压型钢板+钢梁+混凝土）。根据本工程建设地点土层的具体情况，考虑基坑支护立柱桩和调沉桩共同作用，对地基与基础进行了协同分析计算，以解决沉降不均匀问题。介绍了地下室设计时为解决基坑支护在施工过程及换撑时对结构的影响所采取的措施，并对楼板开大洞及楼板舒适度等结构设计中的一些关键问题采用有限元等手段进行深入分析。［关键词］钢筋混凝土核心筒; 桩基础; 有限元中图分类号：TU318 文献标识码：A 文章编号：1002-848X(2014)20-0011-05Structural design of Kate Building in BeijingMao Weizhong, Lu Ye, Yu Meng, Zhang Qiao, Zhang Guoqing（Beijing Institute of Architectural Design, Beijing 100045, China）Abstract:The main tower of Kate Building adopts hybrid structural system which is composed of reinforced concrete core wall, steel reinforced concrete columns and steel reinforced beams. Composite floor system is adopted which is composed of profiled steel sheet, steel beams and concrete. Considering the specific soil layers of the project construction site as well as the interaction of foundation pit supporting column piles and adjusted piles, collaborative analysis and calculation were made on ground and foundation to solve the problem of uneven settlement. Measures which were taken for the effect of foundation pit supporting on main structures in construction process and bracing substitution in basement design were introduced. Further finite element analyses on some key problems such as large openings in floor and the floor comfort were carried out.Keywords:reinforced concrete core wall; pile foundation; finite element作者简介：毛伟中，本科，高级工程师，Email:maowz@vip.sina.com。参考文献［1］北京市地质工程勘察院.凯特大厦岩土工程详细勘察报告［Ｒ］．2011.［2］GB 50007—2011 建筑地基基础设计规范［S］.北京：中国建筑工业出版社，2011.［3］梅国雄，周峰，吴志斌.桩土共同作用的若干实现方法及其应用［M］.北京：科学出版社，2012.［4］北京市勘察设计研究院有限公司.北京英皇凯特大厦新补立柱桩后协同分析结果说明［Ｒ］．2013.［5］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.［6］GB 50011—2010 建筑抗震设计规范［S］.北京：中国建筑工业出版社，2010.［7］建质［2010］109号 超限高层建筑工程抗震设防专项审查技术要点［S］.2010.［8］娄宇，黄健，吕佐超.楼板体系振动舒适度［M］．北京：科学出版社，2012.
