In　order　to　study　the　uniaxial　compressive　behavior　of　different　types　of　fiber　reinforced　polymer　(FRP)　confined　ultrahigh-performance　concrete　(UHPC),　27　FRP-confined　UHPC　specimens　and　3　un-confined　specimens　were　used　for　performing　the　uniaxial　compressive　tests.　The　stress-strain　curves　were　obtained　from　the　testes.　The　effects　of　FRP　types　and　fiber　sheets　number　on　confinement　effectiveness　were　analyzed.　The　test　results　show　that　the　compressive　strength　of　FRP-confined　specimens　mainly　depends　on　the　confinement　ratios,　but　the　ultimate　strain　not　only　depend　on　the　confinement　ratio,　but　also　depend　on　the　types　of　FRP.　The　compressive　strength　and　ultimate　strains　increase　with　the　confinement　ratio.　The　Lam-Teng　model　represented　the　best　fit　for　the　stress-strain　curves.　Based　on　the　test　results,　the　new　models　for　predicting　the　compressive　strength　and　ultimate　strain　were　proposed,　and　those　models　can　more　accurately　predict　the　confinement　responses　of　FRP-confined　UHPC.　©　2016,　Editorial　Board　of　Journal　of　Harbin　Engineering.　All　right　reserved.
