Earthquake-resilient　structures　are　an　ideal　new　direction　for　seismic　design　of　structures.　In　recent　years,　earthquake-resilient　structures　have　gradually　become　a　research　hotspot　in　seismic　field.　Based　on　the　idea　of　damage　control,　this　paper　proposes　a　self-centering　prestressed　prefabricated　steel　beam-column　joint　(SPPSJ)　with　dog　bone　weakened　flange　cover　plate　(FCP).　By　designing　three　sets　of　test　specimens　for　cyclic　loading　test,　the　thickness　of　the　dog　bone　weakened　FCP　and　the　pretension　of　the　cable　were　studied,　and　the　hysteresis　curve,　skeleton　curve　and　cumulative　energy　dissipation　curve　of　the　joint　were　obtained.　Then,　the　reliability　of　the　test　results　is　verified　by　numerical　analysis.　Finally,　the　design　proposals　of　SPPSJ　are　put　forward,　which　is　convenient　for　the　popularization　and　use　of　SPPSJ.　The　results　show　that:　The　SPPSJ　has　good　bearing　capacity,　seismic　performance　and　self-centering　capacity　after　earthquake,　which　can　effectively　dissipate　energy　through　plastic　deformation　of　FCP,　and　realize　post-earthquake　resetting　of　the　joint　through　prestressed　cables.　On　the　premise　of　the　same　load-bearing　capacity,　it　can　obtain　that　the　SPPSJs　with　dog　bone　weakened　FCP　have　better　energy　dissipation　performance　and　lower　requirement　cable　pretension,　which　makes　the　prestressed　cable　maintain　high　safety　factor　during　the　loading　process.　There　is　a　certain　range　of　correspondence　between　the　thickness　of　the　dog　bone　weakened　FCP　and　the　cable　pretension.　When　the　yield　load　ratio　of　the　dog　bone　weakened　FCP　to　high-strength　bolts　on　web　connection　plates　and　the　cables　is　about　3/7,　the　energy　dissipation　capacity　and　self-centering　capacity　of　the　SPPSJ　can　reach　the　best　balance.
