Post-earthquake　structural　repair　combined　with　prefabricated　steel　structures　is　an　important　aspect　of　repairing　buildings　damaged　by　earthquakes　and　has　been　extensively　studied　by　earthquake　engineering　scholars.　Based　on　the　concept　of　plastic　damage　concentration　and　replaceable　damage　elements,　and　considering　the　convenience　of　floor　assembly　and　pipeline　pavement,　an　innovative　earthquake-resilient　prefabricated　opening-web　steel　channel　beam-to-column　joint　(POWSCBCJ)　with　flange　cover　plates　(FCPs)　was　proposed　in　this　paper.　By　varying　four　influencing　parameters　and　applying　three　loading　protocols,　eight　low-frequency　cyclic　loading　tests　were　carried　out　on　eight　full-scale　specimens　of　a　new　type　of　earthquake-resilient　POWSCBCJ.　The　seismic　behavior　and　earthquake-resilient　performance　were　evaluated　by　varying　parameters　such　as　the　thickness　of　the　FCPs,　bolt　spacing　in　the　middle　row,　width　of　the　dog-bone　reduced　sections,　number　of　bolts,　and　loading　system.　The　experimental　results　show　that　the　thickness　of　the　FCPs　is　the　main　factor　affecting　the　yielding　load　and　bearing　capacity　of　the　joint.　In　addition,　an　appropriate　number　of　connecting　bolts　on　the　FCP　and　the　bolt　spacing　in　the　middle　row　are　conducive　to　improving　the　energy　dissipation　ability　of　the　specimen.　At　the　same　time,　the　hysteretic　performance　of　the　joint　is　stable　during　the　process　of　equal　amplitude　loading,　indicating　that　it　can　be　used　as　a　damper.
