This　paper　presents　the　axial　compression　test　results　of　concrete-filled　steel　tubular　(CFST)　stub　columns　strengthened　with　carbon　fiber　reinforced　polymer　(CFRP)　composites.　Both　circular　and　rectangular　specimens　were　tested　to　investigate　the　retrofitting　effects　of　CFRP　composites　on　them.　The　test　results　showed　that　the　CFRP　jackets　enhanced　the　load　bearing　capacity　of　the　circular　columns　effectively,　whereas　the　enhancement　was　not　so　significant　for　rectangular　columns.　However,　ductility　was　enhanced　to　some　extent　for　those　rectangular　columns.　A　simple　model　is　proposed　to　calculate　the　ultimate　strength　of　circular　CFST　stub　columns　wrapped　with　CFRP.　The　predicted　results　are　generally　in　good　agreement　with　the　experimental　ones　obtained　in　this　study　and　in　the　literature.
