［摘要］随着城市的发展，越来越多高层连体结构被广泛建设和应用,其中连接桥的存在可能会引起楼体结构受力特性的改变，对结构的安全稳定造成不良影响。采用ETABS软件建立三维建模，分别沿连接桥方向和垂直连接桥方向施加不同地震作用，分析连接桥的存在及其所处不同位置对结构受力特性造成的影响。结果表明，连接桥的存在对楼体位移、剪力、弯矩等都会造成一定影响，且连接桥所处位置不同造成的影响也不相同，当连接桥位于楼体顶部时，对结构造成的影响最大。

Abstract:With the development of the city, more and more high-rise connected structures have been widely constructed and applied, among which the existence of connecting bridges may cause the change of the bearing characteristics of the building structure to cause adverse effects on the safety and stability of the structure. ETABS software was used to establish 3D modeling, and different seismic effects were applied on the direction along the connecting bridge and the vertical direction to the connecting bridge respectively, to analyze the influence of the existence of the connecting bridge and its different positions on the structural mechanical characteristics. The results show that the presence of the connecting bridge has a certain influence on the displacement, shear force and bending moment of the building, and the influences are different if the the locations of the connecting bridge are different. When the connecting bridge is located at the top of the building, the influence is the greatest on the structure.

Keywords:high-rise connected building; connecting bridge; earthquake action; dynamic response
