張耀康, 周健（華東建筑設計研究院有限公司，上海 200002）［摘要］重賓保利國際廣場位于重慶市渝中區(qū)，建筑高度286.8m，塔樓采用鋼筋混凝土框架-核心筒結構。介紹了項目的結構選型，基礎和地下室、上部結構的設計特點。按不同規(guī)范對核心鋼管混凝土柱的承載力進行了比較計算，根據(jù)風洞試驗結果確定本工程風荷載體型系數(shù)的取值。最后對剛重比的計算和結構重力二階效應進行了分析研究和探討。［關鍵詞］超高層建筑；加強層；核心鋼管混凝土柱；剛重比；重力二階效應中圖分類號：TU375文獻標識碼：A文章編號：1002-848X(2012)05-0053-05Structural design and analysis on Chongbin-Baoli PlazaZhang Yaokang, Zhou Jian (East China Architectural Design & Research Institute Co., Ltd., Shanghai 200002, China)Abstract: Chongbin-Baoli Plaza is 286.8m high, which located at Chongqing Yuzhong district. The RC frame-core wall structural system is used for the tower. The structural form selection, design characteristics of foundation, basement and upper structures were introduced. Bearing capacity of the concrete filled steel tube designed according to different codes was compared, and the wind load shape coefficient was determined by results of wind tunnel test. Finally, the rigidity-gravity ratio and gravity second-order effect were researched and discussed.Keywords: super high-rise building; strengthened story; concrete filled steel tube; rigidity gravity ratio; gravity second-order effect作者簡介：張耀康，碩士，高級工程師，Email: yaokang_zhang@ecadi.com。參考文獻［1］ CECS 188:2005鋼管混凝土疊合柱結構技術規(guī)程［S］.北京：中國計劃出版社，2005.［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］ 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.［4］ 美國混凝土學會(ACI). 美國房屋建筑混凝土結構規(guī)范(ACI 318-05)及條文說明(ACI 318R-05)［M］. 張川, 白紹良, 錢覺時, 等譯. 重慶：重慶大學出版社，2007.
