Combining with a high-rise structure example, structural system selection, overall calculation, seismic elastic time-history analysis and floor stress analysis of connecting parts were discussed. The results show that large torsion deformation under seismic action is tend to happen in the twin-tower connected structure due to irregular facade, so vertical components should be arranged reasonably and corresponding strengthening measures should be taken. The vierendeel truss connection scheme can improve the shear bearing capacity and ductility of structure and guarantee the seismic safety of structure.Keywords: twin-tower connected structure; rigid connection; structural system selection; steel reinforced concrete truss作者簡介：譚希平，本科，高級工程師，Email:251629377@qq.com。參考文獻［1］徐培福，傅學(xué)怡，王翠坤，等.復(fù)雜高層建筑結(jié)構(gòu)設(shè)計［M］.北京:中國建筑工業(yè)出版社，2005.［2］JGJ 3—2002 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，2002.［3］GB 50011—2001 建筑抗震設(shè)計規(guī)范［S］. 北京:中國建筑工業(yè)出版社，2001.［4］YB 9082—2006 鋼骨混凝土結(jié)構(gòu)技術(shù)規(guī)程［S］. 北京:冶金工業(yè)出版社，2007.
