Existing Bridges

The seismic performance of multi-span simply supported steel-girder bridges with sliding and high rocker steel bearings is poor during earthquakes. During the past 20 years, seismic isolation has emerged as one of the most promising strategy for improving the seismic performance of existing bridges. In this study elastomeric bearings, lead-rubber bearings, and cable restrainers are attempted to modify the seismic response of bridges, and theirs effects are analyzed and compared.
