| 摘 要： | 以某桥梁工程为背景,建立空间有限元计算模型,对比分析了桥梁结构在有无减隔震措施下的地震反应。结果表明,未采取减隔震措施时,该桥桥墩会发生强度破坏;而采用摩擦摆减隔震支座后,该桥桥墩的强度、变形均能满足规范要求。该计算结果可为同类桥梁结构的减隔震设计提供参考。

| Abstract: | The finite element model is established to contrast the seismic response of the bridge with or without seismic mitigation and isolation system based on the background of a bridge project. The results show that strength failure will occur on the pier without the seismic mitigation and isolation measures. However, the strength and deformation of the pier can meet the requirements of the specifications concerned while the friction pendulum bearings are used. The results can be used as a reference for the design of similar bridge structure. |
