Prefabricated　steel　structure　has　been　promoted　in　construction　for　its　advantages　in　the　greening,　industrialization　and　informatization　of　buildings.　Meanwhile,　the　earthquake-resilience　of　steel　structures　has　become　a　research　hotspot　in　the　field　of　international　seismic　engineering.　In　this　paper,　five　earthquake-resilient　prefabricated　steel　beam-column　cross　joints　(ERPCJs)　were　studied　by　the　low-cyclic　loading　tests.　The　influence　of　flange　connecting　bolts　number,　flange　connection　forms,　bolt　distance　of　middle　row　and　bolt　hole　forms　on　the　seismic　performance,　failure　mode　and　other　key　performance　indexes　were　studied.　The　tests　results　show　that　ERPCJs　with　reasonable　parameters　have　outstanding　bearing　capability　and　seismic　behavior.　The　beams　of　each　specimen　were　damaged　slightly　or　basically　free　from　damage.　Also,　earthquake-resilient　requirement　could　be　quickly　achieved　by　replacing　connecting　plates　and　high-strength　bolt　groups.　Reducing　the　connecting　bolts　could　make　the　joint　fully　utilize　the　sliding　friction　of　flange　cover　plates　(FCPs)　to　dissipate　energy,　and　enhance　ductility　and　rotation　of　the　joint,　but　it　could　reduce　joint＇s　initial　stiffness　and　ultimate　bearing　capability　at　the　same　time.　The　smaller　bolt　distance　of　middle　row　has　little　effect　on　the　yielding　load　of　the　joint,　but　can　improve　joint＇s　ultimate　bearing　capability.　Besides,　slotted　holes　on　the　cantilever　beam　can　avoid　the　stressconcentration　resulting　from　the　compression　of　bolt　rods　and　bolt　hole　walls,　as　well　as　can　also　effectively　realize　sliding　energy　dissipation　of　the　FCPs.
