摘要
以某高烈度区高速公路项目4×30 m预制箱梁为例,采用通用有限元软件建立全桥有限元分析模型,分析桥梁在不同抗震体系、不同支座类型、桥梁结构的地震响应,为桥梁下部结构抗震设计提供参考依据,也为同类工程的抗震设计提供参考。
In this paper,taking the 4×30 m precast box girder of an expressway project in a high-intensity area as an example,the finite element analysis model of the whole bridge is established by using the general finite element software,the seismic response of bridge structure can provide reference for seismic design of bridge substructure and similar engineering.
