摘要

摘要: 为了确立基于弹塑性Pushover分析的桥梁抗震设计方法，该文以三跨连续刚构桥为对象，进行E2地震动作用下的抗震分析。在弹塑性分析中，考虑桥梁的建设场地为II类场地，E2地震动的烈度为8度。为了考察水平加载形式对桥梁抗震性能及设计的影响，在顺桥方向和横桥方向均采用2种加载形式，即基本模态加载和等加速度加载。分析结果表明，水平加载形式对刚构桥抗震性能影响较小。通过研究表明，Pushover能够很好的探明桥梁整体结构的弹塑性状态，进行E2地震作用下的抗震设计。

Abstract: In order to establish the seismic design method for the bridge on the basis of Pushover analysis, continuous rigid frame bridge with 3 spans was exampled to perform seismic analysis under earthquake action E2 in the paper. In the elastio-plastic analysis, the construction site of the bridge was defined as class Ⅱ and the seismic intensity was 8 degree. Two loading types, namely, fundamental mode loading and uniformly acceleration loading, were applied along the longitudinal and lateral directions to demonstrate the effect of the horizontal loading type on the seismic performance and design of the bridge. The analysis results show that the type of the horizontal loading has little influence on the seismic performance of the rigid frame bridge. The method in the paper can investigate the elastic-plastic condition of the overal structure and perform the seismic design for the bridge under earthquake action E2.
