An experimental study of shear behaviour of high strength reinforcedconcrete corbels with and without fibers was investigated. Seventeen high strength reinforced-concrete corbels were tested. The test variables were steel fiber content (Vf%), shear span-to-depth ratio (a/d), concrete strength (fcu), area of main steel reinforcement (Asm) and presence of horizontal stirrups. Test results showed that, addition of steel fibers or/and horizontal stirrups improves both shear strength and ductility of the tested corbels, and results in a more ductile failure mode. Test results were compared with shear strength predicted using ACI 38-08 equations and those proposed by other investigators. Comparison between the experimental and the predicted values of shear strengths showed that the model proposed by G. Campione et. al.[1], satisfactory predicted the ultimate load for high strength fiber reinforced-concrete corbels.
