The tower consists of discontinuous lateral resistant members and plane size setback along the height. Performance-based seismic design was adopted when critical parts and weak parts were carried out elastic analysis under the moderate earthquake and non-yielding analysis under the rare earthquake. Strengthening measures were adopted to ensure seismic requirements of “not collapse under the rare earthquake”.Keywords: complex high-rise building; performance-based seismic design; conversion truss; vertical size changes作者简介：冯铭，硕士，高级工程师，Email：kgjtycw@126.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］中国建筑科学研究院PKPM CAD工程部. 多层或高层建筑结构空间有限元分析与设计软件(墙元模型)SATWE(2010版)［M］. 2011.［4］CECS 230:2008高层建筑钢混凝土混合结构设计规程［S］.北京：中国计划出版社，2008.
