There　have　been　some　studies　on　the　axial　compressive　behavior　of　concrete　columns　reinforced　with　fiber-reinforced　polymer　(FRP)　bars.　But　most　studies　focused　on　normal　concrete　without　fibers.　In　this　paper,　10　concrete　columns　reinforced　with　glass　fiber-reinforced　polymer　(GFRP)　bars　and　polyvinyl　alcohol　(PVA)　fibers　were　designed　to　investigate　the　influence　of　reinforcement　type,　longitudinal　reinforcement　ratio,　spacing　and　size　of　GFRP　ties　on　the　axial　compressive　behavior　of　the　specimens.　Analytical　and　numerical　studies　were　explored　in　this　paper.　The　test　results　indicated　that　the　concrete　column　reinforced　with　GFRP　bars　and　PVA　fibers　(GFRP　PVA-FRC　column)　and　the　concrete　column　reinforced　with　steel　bars　and　PVA　fibers　(steel　PVA-FRC　column)　had　the　similar　failure　processes　and　failure　modes.　The　axial　bearing　capacity　and　brittleness　of　the　GFRP　PVA-FRC　columns　increased　with　the　increasing　longitudinal　reinforcement　ratio.　When　the　volumetric　ratio　was　constant,　the　confinement　efficiency　and　ductility　of　the　specimens　using　GFRP　ties　with　smaller　diameter　and　closer　spacing　were　higher　than　that　using　GFRP　ties　with　larger　diameter　and　larger　spacing.　A　new　stress-strain　constitutive　model　for　PVA　fiber　reinforced　concrete　confined　by　GFRP　bars　was　proposed.　The　numerical　results　showed　that　the　concrete　in　the　columns　reinforced　with　GFRP　longitudinal　bars　and　GFRP　ties　could　give　full　play　to　its　strength.　The　conclusions　could　be　references　for　the　engineering　application.　(C)　2018　Elsevier　Ltd.　All　rights　reserved.
