（北京市建筑設計研究院有限公司， 北京 100045）［摘要］以重慶悅來溫德姆酒店為工程背景，對結構設計過程中的一系列難點展開深入研究和分析，以驗證其結構設計的合理性。酒店位于臨江的斜坡巖面，場地條件復雜。酒店1，2層局部大空間設鋼骨混凝土轉(zhuǎn)換梁以承托上部框架柱，1層大堂內(nèi)設有旋轉(zhuǎn)鋼樓梯，酒店正立面層層收進，屋頂層設單層鋁網(wǎng)殼。對轉(zhuǎn)換梁及其上部結構進行施工模擬驗算以優(yōu)化施工順序，對轉(zhuǎn)換構件單獨進行了彈塑性有限元分析，對收進層鋼筋混凝土斜撐的端部復雜受力節(jié)點進行有限元分析，對旋轉(zhuǎn)鋼樓梯進行三維建模分析及舒適度驗算，分析和計算結果均能滿足設計預期目標。介紹了屋頂層單層鋁網(wǎng)殼的結構布置和特點，并對其進行了整體受力分析及屈曲分析，分析結果顯示，鋁網(wǎng)殼可以滿足承載力和穩(wěn)定性的要求。［關鍵詞］轉(zhuǎn)換梁; 施工模擬; 旋轉(zhuǎn)鋼樓梯; 單層鋁網(wǎng)殼中圖分類號：TU318 文獻標識碼：A 文章編號：1002-848X(2014)20-0016-05Structural design of Chongqing Yuelai Wyndham HotelWei Liqiang, Wei Dong, Shan Ruizeng, Huang Cheng, Zhou Wenyuan（Beijing Institute of Architectural Design, Beijing 100045, China）Abstract: Taking the Chongqing Yuelai Wyndham Hotel as engineering background, research and analysis were carried out on structural design difficulties to verify the rationality of the structural design. The hotel is built on the riverfront composed of inclined rock with complicated site condition. Steel reinforced concrete transfer beams are adopted in partial large space of the hotel′s first and second floor to hold the upper floor′s frame columns. A rotary steel stair is set in the hotel lobby on the first floor. The facade of the hotel has setbacks layer by layer. A single-layer aluminum shell is built on the roof. Construction simulation analysis was carried out on the transfer beam and its upper structure in order to optimize the construction sequence. Elastic-plastic finite element analysis was carried out on the transfer structure individually. The complicated end node of the reinforced concrete brace in the setback floor was also analyzed with the finite element analysis method. Three-dimension modeling, analysis and human comfort checking were carried out on the rotary steel stair. The analysis and calculation results above could meet the respected design targets. The structural layout and characteristics of the single-layer aluminum shell on the roof were introduced, and the overall mechanical analysis and buckling analysis were carried out on it. Results show that the aluminum shell can meet the carrying capacity and stability requirements.Keywords:transfer beam; construction simulation; rotary steel stair; single-layer aluminum shell作者簡介：位立強，碩士，工程師，一級注冊結構工程師，Email：weiliqiang111@163.com。參考文獻［1］衛(wèi)東，周文源，周忠發(fā)，等.重慶國際博覽中心結構設計中的關鍵技術［J］.建筑結構，2013，43(17)：1-8.［2］JGJ 3—2010 高層建筑混凝土結構技術規(guī)程［S］.北京：中國建筑工業(yè)出版社，2011.［3］趙熙元.建筑鋼結構設計手冊［M］.北京：冶金工業(yè)出版社，1995.［4］秦凱，徐福江，柯長華，等.廣州新客站屋頂鋼結構整體穩(wěn)定性分析［J］.建筑結構，2009，39(12)：33-35.［5］JGJ 61—2003 網(wǎng)殼結構技術規(guī)程［S］.北京：中國建筑工業(yè)出版社，2003.
