Some mechanical characteristics of this new structural system were analyzed and researched, including static analysis under gravity, the lateral force distribution between internal and external core under earthquake and the plastic development by pushover analysis. Meanwhile, the arrangement of ribbed stiffener of complex Yshape joints in the hexagonal grid structure was conducted by finite element analysis.Keywords:highrise building; hexagonal grid structure; Yshape joint作者簡介：丁潔民，博士，教授，博士生導(dǎo)師，Email：djm@tjadri.com。參考文獻(xiàn)［1］呂西林主編. 超限高層建筑工程抗震設(shè)計(jì)指南［S］. 上海：同濟(jì)大學(xué)出版社，2005.［2］GB 50011—2001 建筑抗震設(shè)計(jì)規(guī)范［S］. 2008年版.北京：中國建筑工業(yè)出版社，2008.［3］逸仙路25號地塊項(xiàng)目高層建筑結(jié)構(gòu)抗震分析與設(shè)計(jì)送審報(bào)告［R］.上海：同濟(jì)大學(xué)建筑設(shè)計(jì)研究院（集團(tuán)）有限公司（TJAD），2008.
