The seismic performance evaluation and retrofit process are very important in old existing bridge. If the result is not appropriate, then a retrofit process are required. Among a various retrofit method, the seismic isolation is very useful method. Because it can be applied instead of old bearing in bridge.
In this study, effectiveness of seismic isolation is rationally verified. For this purpose, two seismic isolations used widely are selected and pseudo dynamic test are performed. Through the pseudo dynamic tests, it is showed that seismic isolations are reducing the magnitude of the forces transferred to the substructure and shifting the period of the bridge.
