This　paper　aims　to　experimentally　and　numerically　investigate　the　compressive　behavior　of　circular　concrete　filled　double-skin　steel　tubular　(CFDST)　short　columns,　in　which　only　the　sandwiched　concrete　is　under　axial　compression.　In　total,　28　CFDST　columns　were　loaded　axially,　and　their　axial　load-shortening　curves,　ultimate　strength　and　failure　modes　were　briefly　discussed.　Results　suggest　that　the　wall　thickness　and　yield　stress　of　outer　steel　tube　have　a　significant　effect　on　the　failure　modes,　while　the　concrete　strength　shows　an　insignificant　effect.　The　tested　columns　exhibited　good　ductility　concerned　by　seismic　resistant　design.　The　ultimate　strength　of　the　columns　using　STK490　outer　steel　tubes　was　about　20-26%　than　that　of　ones　with　STK400　outer　steel　tubes.　With　an　increase　in　the　concrete　strength　and　wall　thickness　of　outer　steel　tube,　the　ultimate　strength　of　the　columns　was　improved　by　32%　and　43%,　respectively.　Moreover,　finite　element　(FE)　models　were　established　and　verified　by　comparing　with　the　test　results,　and　then　an　extensive　parametric　analysis　was　carried　out　to　ascertain　the　effects　of　key　variables　on　the　compressive　behaviour　of　the　studied　CFDST　short　columns.　Finally,　based　on　the　numerical　and　test　results,　a　novel　formula　was　proposed　to　estimate　the　ultimate　strength　of　CFDST　columns,　and　high　prediction　performance　was　found　in　the　proposed　formula.　The　proposed　formula　is　not　only　applicable　for　the　strength　prediction　of　CFDST　columns,　but　also　for　that　of　steel　tube　confined　concrete　(STCC)　columns.
