摘要：

Based　on　the　experiment　of　concrete　circular　columns　confined　by　hybrid　fiber　sheets　of　carbon　FRP　(CFRP)　sheet,　aramid　FRP　(AFRP)　sheet,　glass　FRP　(GFRP)　sheet,　fiber　reinforced　Basalt　polymer　(BFRP)　sheet　under　axial　compression,　this　paper　analyzes　failure　configuration,　bearing　capacity,　peak　strain　and　stress-strain　curve.　Experimental　results　show　that:　1)　Comparing　with　the　specimen　without　being　confined,　bearing　capacity　of　specimens　confined　by　1C/1G,　1C/1B　and　1A/1B　improves　154%,　134%　and　140%　respectively,　peak　strain　improves　393%,　363%　and　476%　respectively;　2)　Bearing　capacity　of　specimens　confined　by　1C/2G,　1C/2B　and　1A/2B　improves　187%,　190%　and　170%　respectively,　peak　strain　is　improving　567%,　511%and　574%　respectively;　3)　Bearing　capacity　of　specimens　confined　by　2C/1G,　1C/1A/1G　and　1C/1B/1G　improves　245%,　233%　and　157%　respectively,　peak　strain　improves　649%,　581%　and　426%　respectively;　4)　Based　on　experimental　data,　confining　coefficient　is　presented　to　be　3.1;　5)　A　tri-linear　model　is　presented　to　predict　the　stress-strain　response　of　concrete　circular　columns　confined　by　HFRP.　The　theoretical　curves　agree　well　with　the　experimental　data.
