摘　　要：随着城市的发展,桥梁抗震已成为现代桥梁设计师最关心的问题。在高地震烈度区,为减小地震效应对结构的影响,采用了减隔震支座。现运用有限元软件midas,对E1及E2地震作用下的桥梁结构进行了研究,为以后的抗震设计工作提供了重要的参考依据。With the rapid urbanization,seismic resistance of bridges has become a paramount concern for contemporary bridge designers.In regions with high seismic intensity,seismic isolation bearings has been used to mitigate the impact of seismic effects on the structure.The bridge structures has been studied under E1 and E2 earthquakes using the finite element software Midas.providing valuable insights for future seismic design.
