Earthquake-resilient　functionality　has　become　a　leading　issue　in　seismic　engineering,　and　as　an　important　component　of　earthquake-resilient,　cross　joints　have　become　a　research　hotspot.　A　new　type　of　earthquake-resilient　prefabricated　cross　joint　(ERPCJ)　with　L-shaped　plates　for　damage　control　have　been　proposed　in　this　study.　The　new　type　of　prefabricated　cross　joint　is　constructed　of　a　circular　tubular　steel　column　with　a　cantilever　beam,　a　common　beam,　and　a　connection　device　consisting　of　a　flange　cover　plate,　L-shaped　plates,　and　high-strength　bolt　groups.　By　controlling　the　thickness　of　the　flange　cover　plate　and　the　distance　of　the　middle　bolt,　the　rigidity　of　the　connection　can　be　adjusted　so　that　the　frictional　sliding　of　the　bolt　and　the　plastic　deformation　of　the　flange　cover　plate　can　dissipate　energy　and　ensure　that　the　beams,　columns,　and　other　primary　components　do　not　undergo　plastic　failure.　To　study　the　seismic　performance　and　earthquake-resilient　performance　of　this　new　type　of　cross　joint,　three　specimens　were　designed　and　fabricated.　Unequal　amplitude　low　cyclic　loading　tests　were　carried　out　on　the　three　designed　specimens,　while　30　laps　of　an　equivalent　amplitude　low　cyclic　loading　test　was　carried　out　on　a　repaired　specimen.　The　hysteresis　curves,　skeleton　curves,　and　failure　modes　of　the　specimens　were　obtained.　The　effect　of　the　distance　of　the　middle　bolt,　shape　of　the　bolt　holes,　and　repair　test　on　the　seismic　performance　of　the　joints　were　investigated.　The　experimental　results　indicate　that　the　joint　can　effectively　utilize　the　plastic　deformation　of　the　flange　cover　plate　and　the　sliding　of　the　bolt　for　energy　dissipation.　Adjusting　the　middle　bolt　distance　had　a　significant　effect　on　the　bearing　capacity　and　energy　dissipation　capacity　of　the　joint.　Changing　the　form　of　the　bolt　hole　from　circular　hole　to　slotted　hole　effectively　improves　the　ductility　of　the　joint.　The　repaired　joint　retained　its　good　energy　dissipation　capability,　indicating　that　the　joint　has　a　good　post-earthquake　restoring　performance　and　can　be　used　as　a　displacement-control　damper.
