In　order　to　study　the　performances　of　high-strength　concrete　beams　including　steel　fibers　and　large-particle　recycled　aggregates,　four　different　beams　have　been　designed,　tested　experimentally　and　simulated　numerically.　As　varying　parameters,　the　replacement　rates　of　recycled　coarse　aggregates　and　CFRP　(carbon　fiber　reinforced　polymer)　sheets　have　been　considered.　The　failure　mode　of　these　beams,　related　load　deflection　curves,　stirrup　strain　and　shear　capacity　have　been　determined　through　monotonic　loading　tests.　The　simulations　have　been　conducted　using　the　ABAQUS　finite　element　software.　The　results　show　that　the　shear　failure　mode　of　recycled　concrete　beams　is　similar　to　that　of　ordinary　concrete　beams.　The　shear　carrying　capacity　of　high-strength　concrete　beams　including　steel　fibers　and　large-particle　recycled　coarse　aggregates　grows　with　an　increase　in　the　replacement　rate　of　recycled　coarse　aggregates.　Reinforcement　with　CFRP　sheets　can　significantly　improve　the　beam’s　shear　carrying　capacity　and　overall　resistance　to　deformation.　©　2021
