In order to guarantee the rationality and the certainty of the structural analysis, comparison analyses using multiple programs under the frequent earthquake were carried out as well as elastic time-history analysis under the frequent earthquake and Pushover analysis under the rare earthquake. The comparison analysis results show that structure performs reasonable and elastic under the frequent earthquake, which can satisfy seismic fortification goal of not damage under the frequent earthquake. The structure enters plastic stage under the fortification earthquake without plastic damage in key components. The plasticity of the structure develops quickly and most of energy-dissipated components enter yield stage without overall collapse, which can satisfy the expected seismic fortification goal. The design of skip-floor column was discussed as well.Keywords: L-shaped plan; elastic time-history analysis; Pushover analysis; seismic performance design作者简介：雷兵，硕士，Email：lquanli@126.com。参考文献［1］GB 50223—2008 建筑工程抗震设防分类标准［S］.北京: 中国建筑工业出版社，2008.［2］GB 50153—2008 工程结构可靠性设计统一标准［S］.北京: 中国建筑工业出版社，2009.［3］GB 50011—2010 建筑抗震设计规范［S］.北京: 中国建筑工业出版社，2010.［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.［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］袁雅光.稀柱框架-核心筒结构体系抗震性能分析研究［D］.上海：同济大学，2009.［7］GB 50010—2010 混凝土结构设计规范［S］. 北京: 中国建筑工业出版社，2011.［8］傅学怡.实用高层建筑结构设计［M］.2版.北京：中国建筑工业出版社，2010.［9］胡海涛，张吉明，丁新海，等.烟台阳光100城市广场结构设计［J］.建筑结构，2013，43(1):22-26,47.［10］唐兴荣.高层建筑转换层结构设计与施工［M］.北京：中国建筑工业出版社，2002.［11］JANGID R S, KELLY J M.
