This　paper　aims　to　investigate　the　mechanical　properties　of　concrete-filled　glass　fiber　reinforced　plastic　(GFRP)　tubular　stub　columns　after　being　subjected　to　freeze-thaw　cycles　(FTCs).　A　total　of　72　concrete-filled　GFRP　tubular　(CFGT)　stub　columns　treated　with　different　FTCs　were　tested　under　axial　load.　The　ultimate　capacity,　initial　stiffness,　load-displacement　curves,　load-strain　curves,　and　failure　modes　were　obtained　and　analyzed.　Test　results　indicated　that　the　failure　phenomena　of　the　specimens　under　axial　compression　were　similar,　mainly　including　the　fracturing　of　GFRP　tube　and　crushing　of　core　concrete.　The　FTCs,　concrete　strength　and　column　height　all　had　a　significant　influence　on　the　failure　modes　of　the　specimens.　The　ultimate　capacity　and　initial　stiffness　decreased　evidently　with　the　increase　of　the　number　of　FTCs.　By　increasing　the　height　of　the　column,　the　ultimate　capacity　and　deformation　capacity　of　square　column　after　FTCs　could　be　effectively　improved.　The　change　of　ultimate　capacity　of　the　CFGT　column　after　FTCs　was　the　result　of　the　combined　effect　of　FTCs,　concrete　compressive　strength　and　column　height.　Finally,　the　simplified　formulas　for　calculating　the　ultimate　capacity　of　CFGT　stub　columns　after　FTCs　were　proposed.
