高烈度区现代有轨电车桥梁延性抗震设计

The seismic ductility design of modern tram bridge in high seismic intensity area

现代有轨电车属于新型轨道交通,在高烈度地区修建还没有明确的抗震设计标准。延性抗震作为抗震设计的主要方法,得到国内外广泛的应用。以某高烈度区有轨电车桥梁独柱墩为例,结合GB 50111—2006铁路工程抗震设计规范(2009年版)和CJJ 166—2011城市桥梁抗震设计规范进行延性抗震设计分析,为今后类似工程建设提供参考。

Modern tram belongs to a new type of rail transit,and there is no clear seismic design standard for construction in high earthquake intensity area.Ductility seismic design as a main method of seismic design,has been widely used at home and abroad.In this paper,taking the single column pier of tram bridge in a high intensity area as an example,the ductility seismic design analysis is carried out in combination with Code for Seismic Design of Railway Engineering(GB 50111—2006)(2009 Edition)and Code for Seismic Design of Urban Bridges(CJJ 166—2011),so as to provide reference for similar engineering construction in the future.
