The structure was analyzed by several structural design programs. Through the discussion of structural plan, structure calculation and connections between concrete and steel, project features and calculation analysis were introduced. Hoop stress characteristic of ring-like planar configuration buildings, combined actions and co-deformation between different materials and systems were focused. The project difficulties were solved such as oversized displacement of each floor’s gravity center and connections between steel trusses and the concrete tube.Keywords: composite structure; gravity center; hoop stress; structural design作者簡介：馬牧，高級工程師，一級注冊結(jié)構(gòu)工程師， Email：mmw_0_0@126.com。參考文獻［1］GB 50017—2003 鋼結(jié)構(gòu)設(shè)計規(guī)范［S］.北京：中國計劃出版社，2003.［2］JGJ 138—2001 型鋼混凝土組合結(jié)構(gòu)技術(shù)規(guī)程［S］.北京：中國建筑工業(yè)出版社，2001.
