摘要
结合轻轨桥梁实例,建立了空间有限元仿真模型,对其进行了相应的动力反应谱分析,验算了其在多遇和罕遇地震作用下的抗震性能,结果表明该处桥墩在多遇地震作用下满足规范设计要求,在罕遇地震作用下,顺桥向可能发生损伤,分析结果可为该桥的设计提供指导。
Combining with the light rail case, the paper establishes the spatial finite element model, undertakes the respective dynamic reaction spectrum analysis, calculates the anti-seismic performance of the frequent and rare earthquakes, proves by the result that the bridge piers meet the demands of the regulation design of the frequent earthquakes, and indicates the damages may occur along the bridge, so the analysis results can provide some direction for the bridge design.
