为了了解刚构悬臂梁桥的动力特征和抗震性能,本文利用两种应用最为广泛的抗震分析方法 --反应谱法和时程分析法对泸州长江一桥进行了E1地震作用下的抗震分析,分析结论可以为同类桥梁提供参考借鉴。
In order to understand the dynamic characteristics and seismic performance of rigid-framed cantilever beam bridges, this paper presents two kinds of seismic analysis methods-response spectrum method and time-history method. The seismic analysis of Luqiao Yangtze River Bridge under E1 earthquake is carried out. The conclusion of the analysis can provide reference for similar bridges.
