To　investigate　the　hysteretic　behaviour　of　(carbon)　steel-reinforced　concrete-filled　(rectangular)　stainless　steel　tubular　(SRCFSST)　specimens,　lateral　cyclic　tests　were　performed　on　nine　SRCFSST　or　concrete-filled　(rectangular)　stainless　steel　tubular　(CFSST)　specimens.　The　tests　revealed　that　the　rectangular　SRCFSST　columns　suffered　slight　concrete　damage　due　to　the　confinement　of　the　carbon　profiled　steel　(CPS).　The　use　of　CPS　made　the　hysteretic　loops　of　the　composite　columns　plumper.　The　lateral　carrying　capacity,　ductility　index,　energy　dissipation　coefficient,　cumulative　dissipated　energy,　and　flexural　stiffness　of　the　composite　specimens　increased　by　an　average　of　25.3　%,　13.4　%,　16.1　%,　71.8　%,　and　88.4　%,　respectively.　A　finite　element　(FE)　model　of　the　rectangular　SRCFSST　specimen　was　constructed　to　analyse　the　influence　of　the　CPS　and　the　parametric　effects　on　its　hysteretic　performance.　The　FE　parametric　analysis　reveals　that　increasing　the　stainless　steel　ratio,　carbon　steel　ratio,　material　strength,　or　rotation　radius　significantly　increases　the　bearing　capacity　of　the　SRCFSST　specimen.　Finally,　the　lateral　load　versus　displacement　hysteretic　models　of　the　rectangular　SRCFSST　specimen　were　refined.
