The system and feature of the main structure were described. Analysis results of the crossover were emphatically introduced. Strengthened design measures were put forward corresponding to influence of slab thickness, the control of twin-tower subsidence differences, the prevention of the progressive collapse and the construction process simulation. These measures include improving the stiffness and strength of each tower and setting proper construction process before the form of the stiffness of crossover.Keywords: complicated high-rise building; multi-tower structure; design of the crossover作者簡介：嚴敏，高級工程師，Email:min_yan@ecadi.com。連體結構是復雜高層建筑中較為典型的類型，通常意義上的連體結構分為弱連接結構和強連接結構，強連接結構大多通過連接體將兩棟或多棟塔樓進行剛性連接。已建成的連體結構中由兩個非對稱單塔進行剛性連接的超高層建筑并不多見，其連接體部分的設計和分析尤為重要。本文將結合作者的工程設計實踐，介紹非對稱剛性連體超高層建筑——蘇州“東方之門”結構工程的設計體會。參考文獻［1］ 嚴敏，張家華，芮明倬，等.非對稱門式雙塔連體超高層結構計算分析［J］. 建筑結構，2008,38（12）：84-86.［2］ 徐培福，傅學怡，王翠坤，等. 復雜高層建筑結構設計［M］. 北京:中國建筑工業(yè)出版社,2005.［3］ 吳曉涵，劉東澤，芮明倬，等. 非對稱剛性連體超高層結構彈塑性時程分析［J］. 建筑結構學報，2010,32（6）:1-9.
