Taking four real projects as examples, the reasons causing weak parts under the rare earthquake were adequately explained combined with studying the structural characteristics. Moreover, according to the problems mentioned, specific strengthening measures were suggested. The re-calculation results show that significant improvement of the structural weak parts is obtained, which further validates the reasonableness of the specific strengthening measurements.Keywords: performance-based seismic design; weak part; structural characteristic; strengthening measure作者简介：林超伟, 博士研究生, 高级工程师，一级注册结构工程师, Email:wei65125036@163.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］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.［3］林超伟, 王兴法, 汪洋, 等. 某特别不规则的框支剪力墙结构抗震性能设计［J］. 建筑结构,2012,42(S2):270-273.［4］CECS 160∶2004 建筑工程抗震性态设计通则(试用)［S］. 北京：中国计划出版社, 2004.［5］虹湾花园结构超限高层抗震设计可行性论证报告［R］. 深圳：香港华艺设计顾问（深圳）有限公司, 2012.［6］林超伟. 基于MIDAS BUILDING软件的动力弹塑性方法应用［J］. 工程抗震与加固［7］深圳湾生态科技园四区结构超限高层抗震设计可行性论证报告［R］. 深圳：香港华艺设计顾问（深圳）有限公司, 2012.
