［摘要］对于刚性连接的连体结构，由于两个塔楼之间存在相互作用，在水平地震作用下其内力和变形与普通高层结构不同，若塔楼为非对称形式，则其受力将更为复杂。将刚性连接的非对称双塔连体结构抽象成为二维质点弹簧梁单元模型，运用弹性时程分析方法进行分析和研究，通过参数分析得到了此类结构在地震作用下的内力和变形分布的一般规律。［关键词］连体结构; 地震响应; 有限元; 时程分析; 参数分析中图分类号：TU973.3+1 文献标识码：A 文章编号：1002-848X(2015)20-0022-06
Seismic response study on asymmetrically connected double-tower structuresYang Jiaqi1, Wang Hanbing2, Yu Yinquan2(1 Country Garden Group, Foshan 528311, China; 2 China Institute of Building Standard Design and Research, Beijing 100044, China)Abstract: For the rigid connection, due to the interaction between two towers, the internal force and deformation are different from those of the normal high rise buildings when subjected to lateral earthquake action. If the two towers are asymmetric, the load distribution becomes even more complex. A connected double-tower structure with asymmetric towers and rigid connection was modeled by 2D point mass-shear spring-flexural beam finite element model and analyzed via elastic time-history method. After series of parametric studies, the distributions of deformation and internal force of this kind of structure under the earthquake action were presented.Keywords: onnected structure; seismic response; finite element; time-history analysis; parametric analysis作者简介：杨家琦，博士，Email：yangjq1986@163.com。
