Stoppers are often installed with the isolation bearings in bridges to avoid that the upper girder drop from the pier during earthquakes. In this paper a novel energy-dissipation stopper is proposed. The stopper remains elastic and provides reaction force to restrain the displacement of upper girder during small earthquakes. On the other hand when large earthquakes occur it can yield and dissipate energy, and reduce the seismic responses of the bridge. To verify the performance of the stopper, 5 specimens are designed and the experiment study is carried out. The results show that a reasonable designed stopper has reliable strength and can provide adequate energy dissipation capacity.
