To　improve　the　seismic　performance　of　continuous　girder　bridges　(CGBs),　a　novel　Winding　Rope　Fluid　Viscous　Damper　(WRFVD)　is　proposed　and　implemented.　In　this　study,　the　hysteretic　properties　of　WRFVD　are　investigated　through　dynamic　performance　tests.　The　theoretical　mechanical　model　of　WRFVD　is　revised　based　on　the　test　results.　The　state-of-the-art　Equivalent　Energy　Design　Procedure　(EEDP)　is　adopted　and　modified　to　design　CGB　with　WRFVD.　The　design　procedure　can　achieve　the　performance　objectives　at　different　seismic　intensities　without　iteration.　In　addition,　a　method　for　determining　the　energy　modification　factors　for　CGB　is　established.　A　3-span　prototype　CGB　with　WRFVD　is　designed　using　the　modified　EEDP　presented.　A　series　of　nonlinear　time　history　analyses　are　conducted　to　validate　the　seismic　performance　of　CGB　with　WRFVD.　The　results　demonstrate　that　WRFVD　can　efficiently　achieve　the　seismic　performance　objectives　at　different　seismic　intensities,　thus　validating　the　effectiveness　of　the　modified　EEDP　for　CGBs　with　WRFVD.　©　2025
