强震作用下预制结构桥梁抗震性能研究

本文以功东高速公路某桥为研究对象,基于Midas有限元分析软件建立动力分析模型,分析结构的动力特性,同时,采用反应谱和非线性时程分析方法研究桥墩及桩基在E1、E2地震作用下的地震响应,为同类桥梁的抗震性能分析提供参考。

This paper takes a bridge in Gong shan-Dong chuan expressway project as an example,based on Midas f inite element analysis software,a dynamic analysis model is established to analyze the dynamic characteristics of the structure,At the same time,the seismic response of piers and pile foundations under E1 and E2 earthquake actions is studied by response spectrum and non-linear time history analysis method,it provides reference for seismic performance analysis of similar bridges。
