竖向地震作用下高墩大跨曲线连续刚构桥地震响应分析

摘要

In order to analyze the vertical seismic response,four finite elements based on engineering background of curved continuous rigid -frame bridge with high piers and long spans are established with dif erent vibration character in this paper,some beneficial conclusions are obtained which can provide reference for the research and design of similar bridges.%本文以实际工程为背景，采用有限元软件建立多个变参数模型，分析研究竖向地震作用下，不同曲率半径的高墩大跨曲线连续刚构桥的动力响应和抗震性能，得出有益结论，以便更好的指导工程实践，促进该类桥梁在工程中更广泛的应用。
