Achieving　controlled　damage　and　earthquake　resilience　of　column　foot　joints　is　the　key　to　improving　the　overall　performance　of　the　structure.　Besides,　the　restoring　force　model　of　the　joint　is　the　basis　of　seismic　analysis　of　the　structural　system.　Based　on　the　new　type　of　earthquake-resilient　prefabricated　column　foot　joint　(PCFJ)　with　lateral　force-resisting　energy-consuming　device　(LRECD)　previously　proposed　by　the　authors,　the　seismic　performance　of　PCFJ　is　demonstrated　by　means　of　finite　element　(FE)　simulation,　and　a　total　of　eight　groups　of　42　FE　models　are　designed　to　establish　the　corresponding　restoring　force　model　of　PCFJ　in　this　paper.　The　critical　data,　such　as　skeleton　curves　and　hysteresis　curves,　are　obtained.　Then,　based　on　the　curve　development　law　and　the　test　data　of　full-scale　specimen,　a　tri-linear　simplified　skeleton　curve　model　and　a　three-stage　simplified　restoring　force　model　are　proposed　and　the　key　parameters　are　determined.　The　research　shows　that　the　new　prefabricated　column　foot　joint　has　good　seismic　performance,　energy　dissipation　capacity,　and　it　can　be　used　as　a　damper.　In　the　absence　of　sufficient　test　data　samples,　the　established　modified　simplified　restoring　force　model　is　in　good　agreement　with　the　simulation　results　and　test　results,　which　can　reflect　the　hysteresis　performance　of　this　new　joint　and　provide　a　theoretical　basis　for　the　seismic　analysis　of　PCFJs.
