The　functional　structure　of　earthquake-resilient　has　become　a　frontier　issue　in　the　field　of　structural　seismic　performance.　For　researching　the　performance　of　seismic　and　post-earthquake　resilience　of　earthquake-resilient　prefabricated　sinusoidal　corrugated　web　beam-column　joint　(PSCWJ)　previously　proposed　by　the　author,　the　low　frequency　cyclic　loading　test　and　the　finite　element　(FE)　numerical　verification　have　been　carried　out　on　eight　specimens　in　this　paper.　The　hysteretic　curve,　skeleton　curve,　strain　variation　curve,　ductility,　energy　dissipation　and　other　seismic　performance　indexes　of　this　joint　have　been　obtained.　The　impact　of　weakend　form,　thickness　and　strength　of　the　flange　cover　plate　(FCP),　and　the　gap　between　beams　on　the　joint　seismic　performance　as　well　as　the　post-earthquake　repair　performance　have　been　investigated.　The　results　indicate　that:　the　reasonably　designed　joint　does　well　in　bearing　capacity,　ductility　and　energy　dissipation　capability;　the　quick　repair　of　joint　can　be　realized　by　installing　a　new　connection　device,　and　the　repaired　joint　can　still　meet　the　seismic　performance　requirements;　the　FCP　weakened　by　a　straight　dog-bone　profile　is　better　for　the　joint　plastic　development　and　the　relocation　of　plastic　hinge　at　the　beam　end;　the　gap　properly　set　between　beams　can　effectively　promote　the　rotation　capability　of　the　joint;　the　yield　load　of　joint　is　directly　decided　by　the　thickness　and　the　strength　of　the　FCP.
