In　offshore　structures,　stainless　steel　structures　are　widely　used　in　recent　years.　This　paper　presents　an　experimental　and　numerical　study　on　carbon　steel　reinforced　concrete-filled　stainless　steel　tubular　columns,　which　is　defined　as　CFSCT　(concrete-filled　stainless-carbon　tubular)　stub　columns,　under　local　compression.　A　total　of　25　specimens　were　tested,　the　effects　of　outer　tube　thickness,　concrete　strength,　local　compression　ratio　and　shape　of　bearing　block　on　the　local　compression　performance　were　studied.　The　advantages　of　CFSCT　specimens　over　conventional　design　schemes　were　discussed.　FE　models　were　established　to　verify　the　experimental　results.　Parametric　study　was　conducted　to　consider　a　wider　range　of　geometric　and　material　properties.　The　results　indicate　that　with　the　increase　of　beta,　the　stiffness　of　the　specimen　decreases　and　the　deformation　performance　increases.　When　local　compression　ratio　beta　=　2.25,　increasing　outer　tube　thickness　and　concrete　strength　results　in　an　improvement　in　bearing　capacity　of　21.0%　and　9.6%,　respectively.　When　beta　=　9,　increasing　the　thickness　and　strength　of　inner　tube　proves　to　be　more　effective,　resulting　in　the　highest　increasement　of　81.6%　and　108.7%,　respectively.　The　shape　of　bearing　block　has　little　impact　on　the　bearing　capacity.　Under　the　same　steel　ratio,　SI　values　of　CFSCT　specimens　are　28.8%　and　141.7%　higher　than　those　of　CFSST　specimens　at　beta　=　2.25　and　9,　respectively.　Finally,　the　bearing　capacity　results　were　further　compared　with　current　design　codes,　and　equations　of　evaluating　local　bearing　capacity　were　proposed,　which　shows　good　agreement　with　experiment　results.
