Earthquake-resilient　structures　have　been　widely　recognized　and　applied　in　the　seismic　field　of　prefabricated　steel　structures　due　to　their　excellent　performance.　The　prefabricated　sinusoidal　corrugated　web　steel　beam　column　joint　(PSCWJ)　with　the　earthquake-resilient　design　concept　has　been　previously　proposed.　To　study　the　impact　caused　by　the　bolt　parameters　on　the　seismic　behavior　of　the　new　PSCWJ,　five　specimens　were　designed,　with　varying　the　number　of　flange　connecting　bolts,　type　of　bolt　holes,　and　interval　between　the　middle　bolts.　A　low　cycle　reciprocating　load　test　and　the　finite　element　(FE)　simulations　were　conducted　on　the　specimens　to　determine　the　failure　mode,　energy　dissipation　capacity,　ductility,　hysteretic　curves,　sliding　curves,　strain　curves,　skeleton　curves,　and　other　main　indexes　on　seismic　performance.　And　the　study　indicates　that　the　PSCWJ　has　excellent　bearing　capacity　and　seismic　performance,　the　new　prefabricated　joint　can　realize　the　dual　energy　dissipation　by　buckling　and　sliding　of　the　flange　cover　plate　(FCP),　and　the　number　of　flange　connecting　bolts　directly　determines　the　sliding　load　of　FCPs.　A　rational　interval　between　middle　bolts　can　control　the　buckling　load　of　FCPs　and　provide　the　joint　with　a　satisfactory　bearing　capacity.　The　setting　of　slotted　hole　can　increase　the　rotation　and　energy　dissipation　capacity　of　the　joint.　Further,　the　energy　dissipation　performance　of　the　repaired　specimens　is　stable　under　the　low　frequency　constant　amplitude　loading,　thereby　ensuring　that　the　PSCWJ　can　be　used　as　a　damper.　(c)　2020　Elsevier　Ltd.　All　rights　reserved.
