In　recent　years,　a　large　number　of　long-span　bridges　suffered　great　damage　due　to　the　pounding　during　earthquake.　Hence,　it　is　important　to　analyze　the　effect　of　pounding　on　seismic　performance　of　the　bridge.　A　shaking　tables　test　on　1/10　scaled　continuous　rigid　frame　and　simply-supported　girder　constituted　bridge　is　carried　out　to　investigate　the　bridge　pounding　response　and　to　develop　more　accurate　simulation　models　for　bridge　impact　behavior,　the　damping　devices　and　isolation　bearings.　The　experimental　results　indicate　that　the　traveling　wave　effect　and　the　differences　in　the　stiffness　and　mass　of　the　adjacent　bridge　decks　are　the　reasons　that　induce　the　bridge　impact.　The　isolation　bearings　reduce　the　great　damage　caused　by　bridge　impact.　The　isolation　effect　of　the　lead　rubber　bearing　is　not　always　better　than　the　rubber　bearing　and　it　is　related　to　the　spectrum　characteristics　of　the　ground　motions.　When　the　traveling　wave　effect　is　considered,　the　acceleration　response　obtained　a　larger　peak　while　the　lead　rubber　bearing　is　used.　Meanwhile,　the　reduction　effect　of　viscous　dampers　is　closely　related　to　the　spectrum　characteristics　of　the　ground　motions　as　well.
