摘要
以某城市公轨两用双层桥梁为工程背景,建立有限元计算力学模型,利用反应谱法对该模型进行地震响应分析,并归纳分析其静动力特性。分析结果可为同类桥梁抗震分析及设计提供参考。
With highway and light-railway double-layer bridges in some city as project background, this paper establishes a mechanical model of finite element calculation, analyzes seismic response of the model by means of the response spectrum method and inductively analyzes static and dynamic characteristics of the model. The results of analysis can provide a reference for seismic analysis and design of similar bridges.
