The　increasing　retirement　of　wind　turbines　has　raised　environmental　concerns　regarding　the　disposal　of　waste　wind　turbine　blades.　This　study　investigates　the　reuse　of　recycled　fiber-reinforced　polymer　(FRP)　from　wind　turbine　blades　in　concrete　and　evaluates　the　tensile　and　flexural　properties　of　the　resulting　FRP-fiber　reinforced　concrete　(FRP-FRC).　Uniaxial　tensile　and　three-point　bending　tests　were　conducted　to　assess　the　tensile　and　flexural　strengths　of　concrete　reinforced　with　various　contents　of　recycled　FRP.　The　results　indicate　that　an　optimal　FRP　content　of　1%–1.5　%　enhances　both　the　deformation　capacity　and　strength　of　the　reinforced　concrete.　Additionally,　a　closed-form,　multi-segment　analytical　model　was　developed　to　predict　the　flexural　behavior　of　fiber-reinforced　concrete　(FRC)　under　three-point　bending.　Model　predictions　were　validated　through　comparisons　with　experimental　data　and　numerical　simulations,　demonstrating　excellent　agreement　and　confirming　the　model＇s　reliability.　Parameter　sensitivity　analyses　were　conducted　to　evaluate　the　performance　of　the　analytical　model.　Findings　suggest　that　an　analytical　framework　employing　five-segment　analytical　model　and　an　incremental　step　of　1E-6　ensures　both　predictive　accuracy　and　computational　efficiency.　The　model　also　effectively　captured　the　influence　of　initial　crack　length　on　the　bending　performance　of　FRC　beams.　This　study　provides　a　novel　analytical　method　and　theoretical　framework　for　concrete　reinforced　with　FRP　and　other　fiber　materials.　Furthermore,　it　offers　valuable　insights　into　the　potential　reuse　of　recycled　wind　turbine　blades　in　construction　applications.　©　2024　Elsevier　Ltd
