Based　on　the　design　concepts　of　damage　control　and　concentrated　energy　consumption　of　key　energy-consuming　components,　this　paper　puts　forward　an　earthquake-resilient　prefabricated　column　foot　joint.　Expounds　the　structural　composition,　advantages　and　seismic　design　requirements　of　this　new　type　column　foot　joint　in　detail.　After　comprehensively　considering　the　mechanical　mechanism　of　the　column　foot　joint,　the　load-bearing　capacity　correction　coefficient　and　the　height　ratio　of　lateral　force-resisting　shear　member　(LRSM)　inflection　point　are　introduced,　and　the　design　theory　is　established　accordingly,　including　the　dimension　of　LRSMs,　the　number　of　connecting　bolts　and　the　stiffness　of　connecting　beams.　The　rationality　and　applicability　of　the　proposed　design　theory　are　verified　by　18　groups　of　90　finite　element　models,　and　several　test　specimens.　The　research　shows　that　the　design　theory　proposed　in　this　paper　can　accurately　predict　the　yield　load　and　initial　stiffness　of　the　new　type　column　foot　joint,　and　effectively　control　the　bolt　slip　time　and　the　connecting　beam　failure　time.　The　new　column　foot　joint　designed　according　to　this　design　theory　has　excellent　bearing　capacity　and　ductility.　The　plastic　damage　of　this　joint　can　be　basically　controlled　on　the　lateral　force-resisting　energy-consuming　device　(LRECD),　which　has　the　premise　of　earthquake-resilient.　©　2022　Elsevier　Ltd
