摘要

以多跨简支的直线梁桥为研究对象

在对比分析主要抗震国家现行桥梁抗震设计规范关于结构横向地震反应计算所采用的简化方法的基础上

通过变化跨径比、墩高、桥墩刚度比等主要结构设计参数

对刚性梁模型与柔性梁模型在模拟结构横桥向地震反应方面的合理性进行比较

提出了适用于多跨简支规则直线梁桥横向地震反应计算的合理简化模型

并对简化计算方法进行改进。

Abstract

There are two simplified calculated models for transverse seismic response analysis of regular straight girder bridges at present.In this paper

concrete girder bridges are employed as research object to study the rationality of the rigid beam model and the flexible beam model.The influence of span ratios

pier heights and pier stiffness ratios on seismic response of bridges is also studied in this research.Then the reasonable simplified model for seismic calculation of regular multi-span simply supported bridges is put forward

and the simplified computation method is improved.
