This　paper　presents　an　experimental　study　of　behaviour　of　FRP-strengthened　concrete-filled　steel　tubular　members　subjected　to　compression,　pure　bending　or　combined　compression　and　bending.　The　main　parameters　varied　in　the　test　are:　(1)　sectional　types:　circular　and　square;　(2)　the　number　of　FRP　layers　and　fibre　directions　of　FRP　(uni-directional　and　bi-directional);　(3)　steel　ratio　of　stub　columns;　(4)　slenderness　ratio.　The　test　results　indicates　that　the　FRP　jackets　can　enhance　the　load-bearing　capacity　and　axial　strain　at　the　peak　load　for　circular　columns　effectively,　whereas　the　enhancement　was　less　significant　for　square　columns.　As　for　the　beams　and　beam-columns,　it　seems　the　bi-directional　FRP　jackets　can　enhance　the　load-bearing　capacity　more　evidently　than　the　uni-directional　FRP　jackets.
