Basalt　Fiber　Reinforced　Polymer　(BFRP)　bars　appear　effective　in　reducing　corrosion-related　damage　and　are　gradually　used　as　substitute　for　Steel　bars　in　engineering　practices.　However,　most　of　available　efforts　are　focused　on　the　size　effect　of　BFRP-reinforced　concrete　(BFRP-RC)　deep　beams　without　web　reinforcement,　while　less　efforts　have　been　studied　on　BFRP-RC　deep　beams　with　web　reinforcement.　Moreover,　the　quantitative　influence　of　the　shear-span　ratio　on　the　shear　capacity　of　BFRP-RC　deep　beams　is　always　in　dispute.　The　purpose　of　the　work　is　to　investigate　the　quantitative　influence　of　beam　depth　and　shear-span　ratio　on　the　shear　behavior　of　BFRP-RC　deep　beams　with　web　reinforcement.　A　total　of　sixteen　specimens　were　tested　by　considering　the　beam　depth　(i.e.,　300　mm　similar　to　1200　mm)　and　the　shear-span　ratio　(i.e.,　0.8,　1.3　and　1.8)　as　test　variables.　Twelve　beams　were　reinforced　with　BFRP　bars　while　the　other　four　beams　were　reinforced　with　steel　bars　to　act　as　controls.　The　corresponding　size　effect　of　BFRP-RC　deep　beams　with　web　reinforcement　was　quantitatively　studied,　and　the　applicability　of　current　design　codes　and　scientific　calculation　methods　were　discussed.　The　results　indicate　that:　1)　the　increase　of　shear-span　ratio　reduces　the　nominal　ultimate　shear　strength　but　has　an　ignorable　influence　on　the　size　effect;　2)　the　nominal　ultimate　shear　strength　of　BFRP-RC　deep　beams　decline　by　about　46%　as　the　beam　depth　increases　from　300　mm　to　1200　mm　(both　horizontal　and　vertical　web　reinforcement　ratio　are　0.51%);　3)　the　size　effect　of　FRP-RC　deep　beams　is　not　reasonably　considered　in　current　design　codes,　while,　Jin＇s　theoretical　model　can　scientifically　reflect　the　effect　of　beam　depth　and　shear-span　ratio　on　the　nominal　shear　strength.
