贾勇, 蔡文杰, 彭肇才(中建国际（深圳）设计顾问有限公司， 深圳 518000)［摘要］三亚海棠湾七星级酒店为框架剪力墙结构，高度为144.2m；结构最大悬挑30m，平面狭长，存在扭转不规则、结构偏心率大于0.15、楼板不连续、尺寸突变等超限情况。根据本项目特点进行了时程分析、罕遇地震下的Pushover分析，采用SAP2000进行施工模拟分析，并采用ABAQUS对结构的关键节点进行了有限元分析，证明了结构的合理性，并提出了相应的抗震加强措施。［关键词］超高层结构；大悬挑；时程分析；施工模拟分析；Pushover中图分类号：TU973.1+6 文献标识码：A 文章编号：1002-848X(2013)10-0045-05Structure design on super high-rise building of Sanya Haitangwan seven-star hotelJia Yong, Cai Wenjie, Peng Zhaocai(China Construction (Shenzhen) Design International Co., Ltd., Shenzhen 518000, China)Abstract: Sanya Haitangwan seven-star hotel is a frame-shear wall structure with the height of 144.2m. The hotel has some out-of-codes properties, such as the largest cantilever of 30m, a long and narrow plane, the irregular torsion under earthquake, the structure eccentricity larger than 0.15, discontinuous floors, and the size mutation. The time-history analysis, Pushover analysis under rare earthquake and construction simulation analysis of SAP2000 were taken to analyze the super high-rise building. Key joints were analyzed by ABAQUS software. The rationality of the structure was proved and corresponding seismic strengthening measures were put forward.Keywords: super high-rise building; large cantilever; time-history analysis; construction simulation analysis; Pushover作者简介：贾勇，硕士，工程师，Email:342657480@QQ.com。参考文献［1］JGJ 3—2010 高层建筑混凝土结构设计技术规程［S］.北京：中国建筑工业出版社，2011.［2］GB 50011—2010 建筑抗震设计规范［S］.北京：中国建筑工业出版社，2010.［3］ATC-40 Seismic evaluation and retrofit of existing concrete buildings［S］.
