To　analyze　the　quantitative　effect　of　parameters　such　as　beam　height,shear-span　ratio,and　web　reinforcement　ratio　on　the　shear　capacity　of　fiber　reinforced　polymer　(FRP)reinforced　concrete　short　beams,　and　to　verify　the　rationality　of　the　calculation　method　of　shear　capacity　proposed　on　the　basis　of　tie-arch　model　in　the　early　stage,shear　failure　tests　were　conducted　on　11　basalt　FRP　reinforced　concrete　short　beams,with　a　maximum　beam　height　of　1.　2　m.　The　experimental　results　indicate　that　beam　height,shear-span　ratio,horizontal　and　vertical　web　reinforcement　ratio　have　a　significant　effect　on　the　shear　capacity　of　FRP　reinforced　concrete　short　beams.　When　the　beam　height　increases　from　300　mm　to　1　200　mm,the　non-dimensional　ultimate　shear　strength　of　the　test　beam　decreases　by　46.　7%　.　When　the　horizontal　reinforcement　ratio　increases　from　0　to　1.　0%,the　non-dimensional　ultimate　shear　strength　of　the　test　beam　increases　by　40.　5%　.　The　shear　capacity　calculation　formula　proposed　by　tie-arch　model　can　reasonably　reflect　the　influence　laws　of　factors　such　as　beam　height,shear-span　ratio,and　horizontal　web　reinforcement　ratio.　The　calculation　results　are　better　consistent　with　the　results　of　this　experiment　and　collected　experimental　data.　©　2024　Southeast　University.　All　rights　reserved.
