In　order　to　avoid　the　complex　stress　field　of　traditional　beam-column　joints　caused　by　arranging　end　side　plate　or　support　plate　on　beam　end,　and　realize　the　earthquake-resilient　of　joints,　based　on　the　plastic　damage　control　idea,　a　kind　of　end-plate　type　prefabricated　steel　frame　beam-column　joint　(EPPSFJ)　is　put　forward　in　this　paper.　The　new　type　joint　mainly　consists　of　the　circular　steel　tube　column　with　cantilever　beam,　ordinary　beam,　and　the　connecting　devices.　The　EPPSFJ　can　realize　stiffness　control　of　the　connection　by　adjusting　the　thickness　of　the　flange　cover　plate　(FCP),　the　distance　between　the　middle　bolts　and　other　parameters,　and　make　use　of　the　plastic　distortion　and　friction　sliding　of　the　FCP　to　dissipate　the　seismic　energy,　so　as　to　ensure　the　basic　elasticity　of　the　structural　member　and　realize　the　rapid　post-earthquake　repair　of　the　joint.　In　the　article,　the　low　cycle　load　test　is　carried　out　on　five　specimens　and　one　repair　specimen　to　obtain　the　failure　pattern,　hysteresis　curve　and　strain　curves　of　joints　etc.,　The　impact　rule　of　parameters　such　as　the　thickness　of　cantilever　beam　flange,　the　distance　between　the　middle　bolts,　thickness　and　weakening　form　of　FCP　on　the　seismic　performance　is　researched.　The　experimental　study　shows　that:　the　joints　have　good　seismic　performance　by　reasonably　designing　parameters　of　bolts　and　the　FCP,　and　the　plastic　distortion　is　focused　on　the　FCP　easily　replaced,　which　make　sure　that　plastic　damage　does　not　occur　at　the　structural　member.　The　repaired　spedmen　still　has　great　energy　dissipation　capacity,　ductility　and　other　seismic　performance　indexes,　which　indicates　that　the　joint　can　be　quickly　repaired　post-earthquake　through　replacing　the　FCP　and　other　connecting　devices.　(C)　2020　Elsevier　Ltd.　All　rights　reserved.
