The　traditional　reinforced　concrete　canopy　using　cast-in-place　(CIP)　technology,　is　associated　with　problems　such　as　long　construction　period,　high　environmental　pollution,　and　low　construction　quality.　Prefabricated　assembly　technology,　due　to　its　modern　and　highly　industrialized　characteristics,　provides　a　promising　solution　to　address　the　mentioned　challenges.　In　this　study,　an　innovative　Ultra　High-Performance　concrete　(UHPC)-filled　grouted　corrugated　duct　connection　(UGCDC)　approach　was　introduced　for　prefabricated　canopy　beam-column　joints,　considering　the　structural　characteristics　of　the　canopy.　To　evaluate　the　seismic　behavior　of　canopy　beam-column　joints　utilizing　the　UGCDC　method,　three　comprehensive　full-scale　quasi-static　experiments　were　conducted.　Meanwhile,　relevant　seismic　behavior　indexes　were　extracted　from　the　hysteresis　curve,　and　the　seismic　performance　of　canopy　joints　was　assessed　by　analyzing　the　effects　of　different　research　parameters　on　seismic　behavior　indicators.　In　addition,　based　on　the　OpenSees　platform,　a　fiber　finite　element　model　(FEM)　was　established　that　incorporated　the　bond-slip　behavior　at　the　UGCDC　joint.　The　research　results　indicated　that　the　seismic　behavior　of　canopy　beam-column　joints　using　UGCDC　is　basically　consistent　with　that　of　CIP　joints,　and　setting　a　shear　key　in　UGCDC　joints　can　improve　ductility　by　22.4　%.　In　terms　of　bearing　capacity,　there　is　not　much　difference　among　the　three　specimens,　but　in　terms　of　initial　stiffness,　the　specimen　using　UGCDC　and　shear　key　and　the　specimen　using　UGCDC　have　increased　by　6.0　%　and　9.6　%　compared　to　CIP　specimen,　respectively.　The　developed　FEM　can　predict　the　hysteresis　characteristic　of　canopy　joints　using　UGCDC.　UGCDC　method　is　a　reliable　connection　form　for　canopy　beam-column　connection　joint,　which　is　suitable　for　medium　to　high　intensity　earthquake　areas.　Finally,　a　seismic　performance　assessment　method　of　prefabricated　canopy　beam-column　joints　using　UGCDC　was　proposed.　©　2024　Elsevier　Ltd
