Environmentally　friendly　recycled　aggregate　concrete　(RAC)　is　a　good　alternative　to　natural　aggregate　concrete　(NAC).　The　poor　performance　of　RAC　(e.g.,　relatively　lower　strength　than　its　NAC　counterpart)　that　limits　its　engineering　application　can　be　improved　by　the　lateral　confinement　of　fiber-reinforced　polymer　(FRP).　A　new　type　of　FRP　emerged　in　recent　years　and　made　from　recycled　polyethylene　naphthalate　(PEN)/terephthalate　(PET)　fibers　has　a　large　rupture　strain　(LRS,　typically　greater　than　5%).　It　is　ideal　for　confining　RAC,　especially　to　satisfy　the　ductility　requirements　of　structures　in　earthquake　zones.　In　this　study,　40　RAC　circular　specimens　wrapped　with　LRS　FRP　were　tested　for　monotonic　compressive　behavior.　The　replacement　ratio　of　recycled　coarse　aggregate　and　the　confinement　stiffness　of　FRP　were　experimentally　studied.　Test　results　indicate　that　the　enhancement　of　compressive　strength　and　strain　of　RAC　is　mainly　affected　by　the　confinement　stiffness,　but　marginally　affected　by　the　replacement　ratio.　Furthermore,　the　results　show　that　the　design-oriented　model　and　analysis-oriented　model　previously　developed　by　the　authors＇　group　for　LRS　FRP-confined　NAC,　can　present　satisfactory　predication　performance　on　LRS　FR-Pconfined　RAC.　These　findings　not　only　provide　design　guidance　for　LRS　FRP-confined　RAC　members,　but　also　point　to　the　possibility　of　the　development　of　a　sustainable　structural　system.　(C)　2020　Elsevier　Ltd.　All　rights　reserved.
