This　paper　investigates　the　effect　of　high　temperature　(600　°C,　800　°C,　1000　°C　and　1100　°C)　and　the　layers　of　carbon　fibre　reinforced　plastics　(CFRP)　sheets　(one,　two,　three,　four)　on　the　behaviour　of　fire-exposed　steel　tubular　stub　columns.　Forty　specimens　were　tested　to　investigate　the　failure　modes,　ultimate　bearing　capacity　under　axial　compression,　load-strain　relationship,　load-displacement　relationship　and　initial　stiffness　of　the　specimens.　Ultimate　bearing　capacity　and　initial　stiffness　decrease　with　the　increase　of　temperature.　The　ultimate　bearing　capacity　and　ductility　of　fire-exposed　specimens　wrapped　with　CFRP　sheets　increase　with　the　increase　of　CFRP　sheets　layers.　After　being　strengthened　by　CFRP　sheets　with　the　same　number　of　winding　layers,　circular　steel　tubular　(CST)　stub　columns　obtained　a　greater　load-bearing　capacity　increase　than　square　steel　tubular　(SST)　stub　columns.　The　largest　enhancement　of　the　ultimate　bearing　capacity　of　fire-exposed　specimens　is　59.47%.　A　recommended　formula　for　the　calculation　of　ultimate　bearing　capacity　of　fire-exposed　specimens　wrapped　with　CFRP　sheets　is　proposed.　©　2020
