Concrete-filled　steel　tubes　(CFSTs)　have　become　increasingly　popular　in　civil　engineering　due　to　their　combined　benefits　of　steel　and　concrete.　However,　the　adverse　effects　of　freeze-thaw　cycles　on　structural　performance　in　colder　climates　have　raised　concerns　about　the　long-term　durability　of　CFST　structures　in　these　regions.　This　study　investigates　the　axial　compression　behavior　of　square　CFST　stub　columns　after　exposure　to　freeze-thaw　cycles.　The　paper　thoroughly　reviews　the　impact　of　freeze-thaw　cycles　on　CFST　structures.　Additionally,　it　proposes　a　freeze-thaw　cycle　test　and　an　axial　compression　performance　test　for　54　square　CFST　stub　columns,　considering　three　parameters:　the　number　of　freeze-thaw　cycles,　the　compressive　strength　of　the　concrete,　and　the　wall　thickness　of　the　steel　tube.　The　analysis　focuses　on　the　failure　mode,　load-deformation　relationship,　load-strain　relationship,　ultimate　bearing　capacity,　and　initial　compressive　stiffness　of　the　specimens,　all　correlated　with　the　effects　of　freeze-thaw　cycles.　Finally,　the　accuracy　of　AISC　360–16　and　EC4　specifications　in　predicting　the　ultimate　bearing　capacity　of　square　CFST　stub　columns　subjected　to　freeze-thaw　cycles　is　evaluated.　©　2024
