Abstract：

Aiming　at　problems　of　only　one　fixed　pier　usually　being　set　for　continuous　girder　bridges　and　aseismic　design　being　difficult　to　meet　actual　demands,　a　new　self-reset　seismic　reduction　and　isolation　structure　at　pier　bottom　was　proposed.　The　aseismic　effect　of　the　proposed　structure　at　pier　bottom　was　studied　with　shaking　table　tests　and　finite　element　(FE)　simulation.　Taking　a　typical　3-span　railway　continuous　girder　bridge　as　an　example,　effects　of　the　proposed　structure　at　pier　bottom　on　impact　between　the　main　bridge　and　the　approach　bridge　were　studied　to　analyze　effects　of　site　type,　pier　height　and　peak　seismic　acceleration　on　impact　response.　Results　showed　that　the　proposed　structure　at　pier　bottom　has　good　aseismic　effect,　but　it　may　increase　impact　response　between　the　main　bridge　and　the　approach　one;　site　type　and　pier　height　greatly　affect　its　aseismic　effect,　with　site　type　varying　from　I　to　IV　and　increase　in　pier　height,　its　overall　aseismic　effect　is　more　obvious.　©　2020,　Editorial　Office　of　Journal　of　Vibration　and　Shock.　All　right　reserved.
