天津柳林大桥全桥地震反应谱分析

Full bridge earthquake response spectrum analysis of Tianjin Liulin Bridge

针对柳林大桥桥梁概况,对大桥进行了抗震研究,并介绍了地震反应谱分析方法的基本原理,通过建立柳林大桥全桥有限元模型和反应谱分析,评估了大桥地震作用下的位移和内力响应。

Aiming at the general situation of Liulin Bridge, seismic study of bridge was carried out, and the dement principle of earthquake response spectrum analysis method was introduced. By building finite element model of Liulin Bridge and response spectrum analysis, the shift and internal force response under the earthquake effect of bridge was evaluated.
