［摘要］隨著城市的發(fā)展，越來(lái)越多高層連體結(jié)構(gòu)被廣泛建設(shè)和應(yīng)用,其中連接橋的存在可能會(huì)引起樓體結(jié)構(gòu)受力特性的改變，對(duì)結(jié)構(gòu)的安全穩(wěn)定造成不良影響。采用ETABS軟件建立三維建模，分別沿連接橋方向和垂直連接橋方向施加不同地震作用，分析連接橋的存在及其所處不同位置對(duì)結(jié)構(gòu)受力特性造成的影響。結(jié)果表明，連接橋的存在對(duì)樓體位移、剪力、彎矩等都會(huì)造成一定影響，且連接橋所處位置不同造成的影響也不相同，當(dāng)連接橋位于樓體頂部時(shí)，對(duì)結(jié)構(gòu)造成的影響最大。

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
