（江西省建筑设计研究总院， 南昌 330046）［摘要］高层双塔连体结构受力比一般多塔结构更为复杂。结合某工程实例, 对结构的体型选择、整体计算、地震弹性时程分析及连体部位的楼板应力分析等进行了论述。结果表明，双塔连体结构平立面不规则，在地震作用下将产生较大的扭转变形，应合理地布置竖向构件，并且采取相应的加强措施；空腹桁架连接方案可以提高结构的抗剪承载力和结构延性，保证结构的抗震安全。［关键词］双塔连体结构; 刚性连接; 结构选型; 型钢混凝土桁架中图分类号：TU375 文献标识码：A 文章编号：1002-848X(2014)22-0017-04Structural design of a high-rise twin-tower connected buildingTan Xiping(Jiangxi Architectural Design & Research General Institute, Nanchang 330046, China)Abstract: The high-rise twin-tower connected structure is a kind of structure form with complex mechanism conditions compared with the general multi-tower structure. Combining with a high-rise structure example, structural system selection, overall calculation, seismic elastic time-history analysis and floor stress analysis of connecting parts were discussed. The results show that large torsion deformation under seismic action is tend to happen in the twin-tower connected structure due to irregular facade, so vertical components should be arranged reasonably and corresponding strengthening measures should be taken. The vierendeel truss connection scheme can improve the shear bearing capacity and ductility of structure and guarantee the seismic safety of structure.Keywords: twin-tower connected structure; rigid connection; structural system selection; steel reinforced concrete truss作者简介：谭希平，本科，高级工程师，Email:251629377@qq.com。参考文献［1］徐培福，傅学怡，王翠坤，等.复杂高层建筑结构设计［M］.北京:中国建筑工业出版社，2005.［2］JGJ 3—2002 高层建筑混凝土结构技术规程［S］. 北京:中国建筑工业出版社，2002.［3］GB 50011—2001 建筑抗震设计规范［S］. 北京:中国建筑工业出版社，2001.［4］YB 9082—2006 钢骨混凝土结构技术规程［S］. 北京:冶金工业出版社，2007.
