（中国建筑设计研究院， 北京 100044）［摘要］结合一栋大底盘多塔框支剪力墙超限高层建筑的结构设计过程，针对项目超限情况，采用基于性能目标的抗震设计方法，讨论了结构不同部位的抗震等级，探讨了整体模型与分塔模型的包络设计。通过大量的计算分析以及严格的抗震措施，确保了结构在地震作用下具有良好的抗震性能。［关键词］高层建筑; 大底盘多塔结构; 框支剪力墙结构; 性能化设计中图分类号：TU973.2 文献标识码：A 文章编号：1002-848X(2014)05-0057-05Design and analysis on frame supported shear wall structure with multi-tower and large chassisZhang Genyu, Zhu Bingyin, Zhang Lu, Xiao Yaozu, Liu Chuanning, Li Zheng, Ma Yuhu, Ma Zhenting(China Architecture Design & Research Institute, Beijing 100044, China)Abstract: Based on the structure design process of a frame supported shear wall structure with multi-tower and large chassis, for the conditions of beyond code limits, the performance-based seismic design method was adopted, the concept of different parts of the structure with different seismic grade was proposed, the envelope design of overall model and tower model was discussed. Seismic performance is ensured through a lot of calculation and strict aseismatic measures.Keywords: tall building; multi-tower with large chassis; frame supported shear wall structure; performance-based design作者简介：张根俞，博士，高级工程师，一级注册结构工程师，Email：genyuzhang@163.com。参考文献［1］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.［2］GB 50011—2010 建筑抗震设计规范［S］.北京: 中国建筑工业出版社，2010.［3］朱炳寅.高层建筑混凝土结构技术规程应用与分析［M］.北京：中国建筑工业出版社,2013.［4］娄宇,程辉,施昌.大底盘上对称多塔楼高层建筑的振动分析［J］.建筑结构,2001,31(4):13-15.
