文章对一塔、墩、梁固结的某矮塔斜拉桥进行了动力特性和地震响应分析,根据该桥的结构特点,建立了该桥的空间有限元分析模型,计算桥梁的振动特性,基于反应谱方法计算了该桥在顺桥向、横桥向水平地震响应。文章的计算结果对于改进此类桥梁的结构布局和构造设计及评价桥梁的动力特性和抗震性能具有一定的参考价值。
According to the structural characteristics of the bridge, a finite element analysis model of the bridge is established to calculate the vibration characteristics of the bridge. Based on the response spectrum method, the horizontal seismic response of the bridge in the direction of the bridge and the bridge is calculated. The calculation results of the article have certain reference value for improving the structural layout and structural design of such bridges and evaluating the dynamic characteristics and seismic performance of the bridges.
