The　influences　of　embedded　carbon　profiled　steel　(CPS),　eccentricity　and　slenderness　ratio　on　steel-reinforced　concrete-filled　(rectangular)　stainless　steel　tubular　(SRCFSST)　specimens　were　investigated　by　eccentric　compression　tests.　Test　results　demonstrated　that　the　embedding　of　CPS　improved　the　load-carrying　capacity,　expanded　the　plastic　hinge　range　and　inhibited　the　development　of　concrete　cracks　in　the　rectangular　SRCFSST　columns.　Before　achieving　the　peak　load,　the　majority　of　the　confining　stress　was　presented　in　the　corner　region　of　the　rectangular　stainless　steel　tube.　After　that,　both　CPS　and　rectangular　stainless　steel　tube　delivered　the　confinement.　A　finite　element　(FE)　model　was　developed　to　study　the　effects　of　different　parameters　on　the　axial　load　versus　bending　moment　curves　and　axial　compression　stability　coefficients　of　the　rectangular　SRCFSST　columns.　The　carbon　steel　ratio　and　material　strength　were　the　most　affecting　parameters.　Finally,　a　revised　simplified　model　for　determining　the　eccentric　compression　resistances　of　the　rectangular　SRCFSST　columns　were　developed.　The　predictions　using　the　simplified　model　agreed　well　with　the　test　results　or　FE　results.
