In　this　paper，a　finite　element　（FE）　model　was　used　to　study　the　pure　bending　behaviors　of　the　circular　steel　reinforced　concrete-filled　stainless　steel　tubular（SRCFSST）members.　The　FE　calculation　results　were　in　a　good　agreement　with　the　test　results.　The　flexural　resistance　of　the　typical　circular　SRCFSST　member　was　111.33%　higher　than　that　of　the　concrete-filled　stainless　steel　tubular（CFSST）counterpart.　The　bending　moment　taken　by　the　concrete　of　the　typical　circular　SRCFSST　member　was　also　23.31%　higher　than　that　of　the　CFSST　counterpart.　Owing　to　the　increasing　confinement　on　the　concrete　in　the　compression　zone　formed　by　the　steel　tube　and　the　flange　of　the　profiled　steel，the　concrete　strength　in　the　compression　zone　was　increased　by　about　20%.　The　flexural　stiffness　and　resistance　of　the　circular　SRCFSST　specimen　increased　with　the　concrete　strength，stainless　steel　ratio，profiled　steel　ratio，and　gyration　radius　ratio.　The　flexural　resistance　of　the　circular　SRCFSST　specimen　increased　with　the　yield　strength　of　the　stainless　steel　or　the　profiled　steel.　Simplified　models　for　predicting　the　flexural　stiffness　and　flexural　resistance　of　the　circular　SRCFSST　member　were　finally　proposed.　©　2024　Tongji　University.　All　rights　reserved.
