Quasi-static　tests　on　six　specimens　were　conducted　to　investigate　the　cumulative　damage　performance　of　composite-sectioned　high　strength　concrete-filled　steel　tubular　(CSCFT)　columns.　The　column　specimen　was　subjected　to　axial　compressive　force　and　lateral　reversal　loading　with　ten　cycles　at　each　drift　level.　The　test　indexes　include　the　axial　force　ratio,　thickness　of　square　steel　tube　and　its　width-to-thickness　ratio,　diameter　and　thickness　of　circular　steel　tube.　The　failure　modes　of　the　six　CSCFT　column　specimens　are　almost　same.　Local　buckling　of　square　steel　tube,　crushing　of　concrete　between　the　two　steel　tubes,　and　local　buckling　of　circular　steel　tube　were　occurred　within　a　height　of　300mm　from　the　column　base.　The　damage　extent　of　specimens　was　a　little　bit　severe　than　the　specimens　loaded　with　three　cycles　at　each　drift　ratio.　The　lateral　force-displacement　hysteretic　loops　of　all　specimens　were　plump.　The　nominal　yield　drift　ratio　was　1/154　to　1/124,　the　peak　drift　ratio　was　over　1/80,　and　the　ultimate　drift　ratio　was　greater　than　1/60.　The　seismic　behavior　of　the　specimens　was　about　the　same　as　that　of　the　specimens　loaded　with　three　cycles　at　each　drift　ratio.　It　means　that　the　seismic　behavior　of　the　CSCFT　column　is　stable.　At　the　drift　ratios　of　1/150　and　1/100,　cumulative　damage　of　the　specimens　was　minimal.　At　the　drift　ratios　of　1/75,　1/50　and　1/33,　the　specimens　experienced　cumulative　damage　to　which　the　extent　was　not　significantly　severe.　Increasing　the　thickness　of　square　steel　tube　and　the　thickness　of　circular　steel　tube　would　lead　to　a　reduction　of　degeneration　extent　of　load-carrying　capacity　of　specimens　caused　by　cumulative　damage.
