Elliptical　concrete-filled　stainless　steel　tubular　(CFSST)　columns　are　high-performance　composite　columns　that　have　the　enormous　potentiality　to　be　used　in　composite　construction　in　the　near　future.　However,　to　date,　limited　studies　on　the　performance　analysis　of　such　columns　under　axial　compression　have　been　performed　taking　into　account　the　accurate　material　laws　of　stainless　steel　and　the　confined　concrete.　This　paper　presents　a　mathematical　model　to　investigate　the　axial　performance　of　elliptical　CFSST　short　columns.　Accurate　material　laws　of　stainless　steel　and　the　confined　concrete　are　incorporated　in　the　numerical　modeling　to　capture　their　true　performance.　Independent　test　results　are　utilized　to　validate　the　accuracy　of　the　mathematical　predictions.　A　parameter　study　is　performed　to　study　the　important　column　parameters　on　their　axial　performance.　The　investigations　of　the　accuracy　of　the　existing　design　models　for　CFST　columns　in　designing　axially　loaded　elliptical　CFSST　columns　are　performed　with　the　test　and　numerical　predictions.
