For　resolving　the　difficulty　that　slab-column　system　can　not　be　popularized　in　high-intensity　earthquake　area,　a　new-type　concrete　filled　steel　tubular　column-slab　joint　is　presented　in　this　paper.　The　new-type　joint　is　characterized　by　forming　a　hinge　joint　between　the　steel　tubular　column　and　the　concrete　flat　in　interior　of　building.　And　it　has　no　use　for　horizontal　loads,　which　bore　completely　by　the　concrete　wall　or　column　around　the　building,　but　only　bore　the　vertical　loads　in　the　structure.　For　all　that,　the　joint　should　not　be　destroyed　badly　to　introduce　the　collapse　of　building　after　suffering　a　big　lateral　load　such　as　strong　earthquake.　In　order　to　prove　the　performance　of　the　joint　in　punching　shear　capacity　and　resisting　lateral　displacement,　the　tests　are　put　up　about　two　1/2-scale　interior　column　joint　specimens　subjected　to　low-cycle　reversed　horizontal　load.　And　the　axis　force　in　steel　tubular　column　was　loaded　before　the　low-cycle　reversed　horizontal　load　according　to　the　ratio　of　shearing　force　bringing　from　the　weight　of　superstructure　and　punching　shear　capacity　of　slabs(GSR)　which　includes　three　case:　GSR=0.69,　GSR=0.83　and　GSR=0.93.　The　test　results　are　introduced　including　the　whole　process,　the　values　of　cracking　load,　maximum　load,　failure　load　and　the　punching　shear　failure　model.　Meanwhile　the　hysterisis　loops,　skeleton　curves　and　the　strain　curves　of　steel　bars　along　the　slab　width　are　also　given.　The　experimental　study　has　showed:　(1)　the　joint　has　the　much　punching　shear　capacity　than　the　value　calculated　by　formula　7.7.1-1　of　code　for　design　of　concrete　structures.　(2)　the　relative　displacement　of　the　joint　can　achieve　2%　of　storey　height　which　is　two　times　of　a　frame　structure＇s　story　drift　limit　in　Code　for　Seismic　Design　of　Building　Structure　before　the　specimens　were　destroyed　even　in　high　GSR　case.　(3)The　new　joint　with　a　low　additional　moment　flexion　can　work　well　cooperating　with　column　and　slab.　From　the　experimental　we　can　resulted　that　the　additional　moment　flexion　in　joint　is　enough　low　to　be　regarded　as　a　hinge.　The　structural　form　of　the　connection　is　simple　and　easy　to　use,　while　the　seismic　behavior　of　slab-column　structures　is　better　than　the　common　slab-column　system.　©2010　IEEE.
