［摘要］對于剛性連接的連體結(jié)構(gòu)，由于兩個塔樓之間存在相互作用，在水平地震作用下其內(nèi)力和變形與普通高層結(jié)構(gòu)不同，若塔樓為非對稱形式，則其受力將更為復(fù)雜。將剛性連接的非對稱雙塔連體結(jié)構(gòu)抽象成為二維質(zhì)點(diǎn)彈簧梁單元模型，運(yùn)用彈性時程分析方法進(jìn)行分析和研究，通過參數(shù)分析得到了此類結(jié)構(gòu)在地震作用下的內(nèi)力和變形分布的一般規(guī)律。［關(guān)鍵詞］連體結(jié)構(gòu); 地震響應(yīng); 有限元; 時程分析; 參數(shù)分析中圖分類號：TU973.3+1 文獻(xiàn)標(biāo)識碼：A 文章編號：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作者簡介：楊家琦，博士，Email：yangjq1986@163.com。
