張耀康，王 帥，周 健（華東建筑設計研究院有限公司，上海 200002）［摘要］成都大魔方演藝中心小陀螺結構為異形支撐鋼框架-混凝土筒體結構，下小上大，造型獨特。外圍框架呈傾斜向上態(tài)勢，筒體布置分散偏置，內部豎向構件不連續(xù)，層４采用網架結構進行轉換。從幾何形狀和極限承載力兩個方面對結構進行穩(wěn)定性分析，結合彈塑性時程分析結果，對筒體、樓板等有針對性地采取了加強措施，確保了結構體系的合理性。［關鍵詞］網架；轉換結構；極限承載力；結構抗傾覆能力中圖分類號：TU392-1文獻標識碼：A文章編號：1002-848X(2012)05-0140-05Structure selection and design of the Music Concert of Chengdu Large Magic Cube Performing Arts CenterZhang Yaokang, Wang Shuai, Zhou Jian(East China Architectural Design & Research Institute Co., Ltd., Shanghai 200002, China)Abstract: The Music Concert of Chengdu Large Magic Cube Performing Arts Center is like a gyro, which grows greater from bottom to top. The braced steel frame-concrete tube structure system is adopted, and the inclined frame and the tube support the system. As the discontinuity of inner vertical columns, the 4th floor takes grid structure to support the above column. With the stability analysis based on the geometry shape and the ultimate capacity, combined with the elasto-plastic time-history analysis, strengthening measures were adopted on tube and deck etc. to reach a reasonable structure.Keywords: grid structure； transfer structure； ultimate bearing capacity； resisting overturning ability作者簡介：張耀康，碩士，高級工程師，Email:yaokang_zhang@ecadi.com。參考文獻［1］GB 50011—2010 建筑抗震設計規(guī)范［S］.北京: 中國建筑工業(yè)出版社, 2010.［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］FEMA 273, FEMA 274, FEMA 356.
