RESEARCH ON THE DYNAMIC PERFORMANCE OF RAILWAY BRIDGE WITH DEFORMATION RESTRICT SEISMIC ISOLATION BEARINGS
A new type seismic isolation bearing with deformation restriction function had been designed by setting soft steel dampers at both sides of rubber lead bearings for Railway Bridge,which can prohibit the destruction of track system under break load of train and occasional and frequent earthquakes. The rubber lead bearings and soft steel dampers were designed with response spectrum method respectively and accurate FEM modal had been established with ANSYS to compare the response of Non-isolation Bridge,seismic isolation bridge with rubber lead bearing and with seismic isolation bridge with new type bearing under earthquakes. The results show that the new type bearing can restrict the deformation of the track system effectively than the others. The track system remains non-destruction state under occasional and frequent earthquake and has a good seismic isolation effect under rare earthquakes.
