With　the　rapid　development　of　prefabricated　structures,　higher　requirements　have　been　placed　on　the　construction　convenience,　seismic　performance,　and　recoverability　of　prefabricated　beam-column　joints.　This　paper　proposes　a　novel　prefabricated　self-centering　RC　beam-CFDST　column　(PSC)　joint,　which　eliminates　the　need　for　on-site　prestressed　steel　strand　tensioning　and　dissipates　energy　through　a　friction　device,　aiming　to　enhance　construction　efficiency　while　improving　the　self-centering　performance　and　energy　dissipation　capacity　of　the　structure.　To　evaluate　its　seismic　performance,　two　PSC　joints　and　one　conventional　self-centering　(SC)　joint　were　designed　and　fabricated.　Low-cycle　reversed　loading　tests　were　conducted　to　investigate　their　hysteretic　behavior　and　to　analyze　the　influence　of　different　connection　forms　on　the　seismic　performance　of　the　joints.　On　this　basis,　a　finite　element　model　of　the　PSC　joint　was　developed　in　OpenSees　and　validated　against　the　experimental　results.　Parameter　analyses　were　further　carried　out　to　study　the　effects　of　steel　strand　prestress,　steel　strand　diameter,　and　exposed　I-beam　length　on　the　hysteretic　performance　of　the　joints.　In　addition,　the　restoring　force　model　was　theoretically　derived　and　verified.　The　results　show　that　the　steel　strands　of　the　PSC　joints　remained　elastic　at　the　maximum　story　drift　of　4　%　and　exhibited　self-centering　performance　comparable　to　and　as　stable　as　that　of　the　SC　joint.　In　terms　of　energy　dissipation,　the　maximum　equivalent　viscous　damping　coefficient　of　the　PSC　joint　reached　13.4　%,　significantly　higher　than　the　9.9　%　of　the　SC　joint.　The　parameter　analysis　indicated　that　the　steel　strand　diameter　had　the　most　significant　effect　on　increasing　load　capacity,　while　steel　strand　prestress　and　exposed　I-beam　length　also　had　positive　effects　on　load　capacity　and　energy　dissipation.　The　proposed　restoring　force　model　showed　good　agreement　with　the　experimental　results　and　can　serve　as　a　reference　for　the　analysis　and　design　of　PSC　joints.　©　2025　Institution　of　Structural　Engineers
