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作者簡介：雷兵，碩士，Email：lquanli@126.com。參考文獻(xiàn)［1］GB 50223—2008 建筑工程抗震設(shè)防分類標(biāo)準(zhǔn)［S］.北京: 中國建筑工業(yè)出版社，2008.［2］GB 50153—2008 工程結(jié)構(gòu)可靠性設(shè)計統(tǒng)一標(biāo)準(zhǔn)［S］.北京: 中國建筑工業(yè)出版社，2009.［3］GB 50011—2010 建筑抗震設(shè)計規(guī)范［S］.北京: 中國建筑工業(yè)出版社，2010.［4］GB 50009—2012 建筑結(jié)構(gòu)荷載規(guī)范［S］.北京: 中國建筑工業(yè)出版社，2012.［5］JGJ 3—2010 高層建筑混凝土結(jié)構(gòu)技術(shù)規(guī)程［S］.北京: 中國建筑工業(yè)出版社，2011.［6］袁雅光.稀柱框架-核心筒結(jié)構(gòu)體系抗震性能分析研究［D］.上海：同濟(jì)大學(xué)，2009.［7］GB 50010—2010 混凝土結(jié)構(gòu)設(shè)計規(guī)范［S］. 北京: 中國建筑工業(yè)出版社，2011.［8］傅學(xué)怡.實(shí)用高層建筑結(jié)構(gòu)設(shè)計［M］.2版.北京：中國建筑工業(yè)出版社，2010.［9］胡海濤，張吉明，丁新海，等.煙臺陽光100城市廣場結(jié)構(gòu)設(shè)計［J］.建筑結(jié)構(gòu)，2013，43(1):22-26,47.［10］唐興榮.高層建筑轉(zhuǎn)換層結(jié)構(gòu)設(shè)計與施工［M］.北京：中國建筑工業(yè)出版社，2002.［11］JANGID R S, KELLY J M.
