In　order　to　investigate　the　seismic　performance　of　earthquake-damaged　high-strength　recycled　aggregate　concrete　(HSRAC)　beam-column　interior　joints　employing　ultra-high　strength　bars　(UHSB)　in　columns,　four　specimens　were　designed　and　manufactured.　The　research　variables　included　whether　the　steel　tube　was　encased　in　the　column　and　whether　beams　were　rehabilitated　by　bonding　steel　plates.　Among　them,　the　rehabilitated　specimens　were　firstly　loaded　to　1.0　%　drift　ratio,　and　then　loaded　to　failure　after　rehabilitating　the　plastic　hinge　of　beams.　The　test　results　showed　that　the　beam　hinge　failure　mode　occurred　in　the　specimens　loaded　directly　to　failure.　The　damage　of　columns　and　joint　cores　was　relatively　slight,　and　the　crack　width　satisfied　the　repairability　limits　before　2.0　%　drift　ratio.　The　shear　failure　of　the　joint　core　occurred　in　the　rehabilitated　specimen　without　steel　tube,　as　shear　deformation　and　stirrup　strain　in　the　joint　core　increased.　The　shear　bearing　capacity　of　joints　increased　after　steel　tubes　were　encased　in　columns,　and　the　damage　of　joint　cores　was　reduced.　The　bearing　capacity　and　deformation　capacity　of　specimens　improved　after　rehabilitating.　Finite　element　models　were　established　and　verified　with　experiment　results.　Parameter　analysis　was　conducted　for　different　pre-　damage　degrees,　and　the　results　indicated　that　as　pre-damage　degree　increased,　the　bearing　capacity　of　specimens　decreased.
