Application of Ultra High Damping Seismic Isolation Bearing in the Seismic Design of Urban Viaduct
In this paper,through the seismic design of urban viaducts in a high seismic intensity area,a three-dimensional dynamic calculation model of the bridge structure is established using the space finite element program MIDAS/civil,and the process of urban viaduct seismic isola-tion design and ultra-high damping seismic isolation bearings are analyzed in detail.Through the analysis of the displacement of the support and the safety of the pier and pile foundation under the action of the E2 earthquake,the effect of the use of the seismic isolation support is veri-fied,and it provides a reference for the seismic design of the same type of bridge.
