To　decrease　the　seismic　response　of　continuous　girder　bridges,　the　seismic　performance　of　a　novel　winding　rope　fluid　viscous　damper　(WRFVD)　was　investigated.　This　device　was　installed　between　the　sliding　piers　and　superstructure,　and　connected　to　the　superstructure　by　winding　ropes.　WRFVD　can　accommodate　the　thermal　deformation　of　superstructure　under　service　condition,　and　make　the　fixed　pier　and　sliding　piers　bear　the　seismic　loads　together　by　establishing　the　friction　connection　between　the　sliding　piers　and　superstructure　under　earthquake　action.　In　this　study,　the　theoretical　mechanism　of　WRFVD　is　derived,　and　verified　by　a　dynamic　performance　test.　A　shaking　table　test　was　conducted　on　a　scaled　three-span　continuous　girder　bridge　employing　WRFVD.　The　test　results　showed　that　WRFVD　can　effectively　reduce　the　seismic　response　of　continuous　girder　bridges.　The　parametric　study　of　WRFVD　on　a　five-span　continuous　girder　bridge　was　investigated.　The　parametric　study　shows　that　the　seismic　response　of　multi-span　continuous　girder　bridge　equipped　with　WRFVD　decrease　with　the　increasing　damping　coefficient　and　friction　coefficient,　and　the　decreasing　damping　index.
