Abstract：

In　order　to　study　the　reinforcement　effect　of　intraply　hybrid　fiber　reinforced　polymer　(IHFRP)　on　concrete　columns,　the　failure　mode,　bearing　capacity,　deformation　performances　and　stress-strain　curves　of　various　IHFRP　confined　concrete　columns　were　analyzed　through　the　tests　for　axial　compression　performances　of　24　concrete　columns.　The　results　show　that　IHFRP　can　significantly　improve　the　bearing　capacity　and　deformation　performances　of　the　columns.　For　the　specimens　confined　with　the　same　layers　of　fiber　reinforced　polymer,　the　bearing　capacity　obviously　increases　with　increasing　the　content　of　carbon　fiber　in　IHFRP.　Compared　with　the　peak　longitudinal　strain　of　the　specimens　confined　with　single　carbon　fiber　reinforced　polymer　(CFRP),　the　peak　longitudinal　strain　of　the　specimens　confined　with　three　kinds　of　IHFRP　gets　enhanced　by　60%　to　100%.　Through　comparing　the　IHFRP　stress-strain　model　with　the　experimental　curves,　it　is　noted　that　the　good　fitting　effect　can　be　obtained.　The　experimental　results　can　provide　the　references　for　the　enhancement　design　of　such　components　as　bridge　pier　columns　and　frame　columns.
