Prefabricated　steel　structure　is　widely　used　as　a　kind　of　green　building　structure　with　life　cycle　significance.　As　the　key　link　in　steel　structure　design,　the　beam-column　joint　design　has　been　deeply　studied.　Based　on　this,　the　paper　proposes　earthquake-resilient　prefabricated　steel　beam-column　joints　(PSBCJs)　with　different　connection　forms.　The　main　components　of　the　joints　are　circle　tubular　steel　column　with　cantilever　beam　and　common　I-beam,　and　the　differences　are　the　change　of　connection　forms　of　flanges　and　webs.　In　this　paper,　five　specimens　were　designed,　and　the　low-cycle　reciprocating　test　and　numerical　simulation　were　carried　out　on　these　specimens　and　the　corresponding　repaired　specimens.　The　parameters　such　as　the　forms　of　flange　cover　plates,　the　forms　of　connecting　plates,　the　middle　bolts　interval　and　the　influence　of　the　earthquake-resilient　behavior　on　the　mechanical　properties　of　the　joints　are　investigated,　and　the　load-displacement　curves,　skeleton　curves　and　damage　models　of　each　specimen　are　obtained.　Test　results　and　numerical　analysis　were　mutually　verified.　The　results　of　the　tests　showed　that　the　new　PSBCJs　can　effectively　dissipate　energy　through　the　plastic　deformation　of　the　flange　cover　plates;　the　middle　bolts　interval　has　a　great　influence　on　the　bearing　capacity　and　energy　dissipation　performance　of　the　joints;　under　the　premise　of　the　same　main　structure,　the　reasonable　changes　of　the　connection　forms　of　the　flange　cover　plates　and　the　web　connectors　have　little　effect　on　the　deformation　mode　of　PSBCJs;　after　the　completion　of　the　loading,　the　main　components　such　as　beams　and　columns　are　basically　kept　elastic,　and　the　seismic　performance　of　the　joints　after　replacing　the　connection　devices　are　still　favorable.
