RESUMO

This work presents a theoretical summary about shear in reinforced concrete beams with addition the steel fiber submitted the reverse loading. Twelve beams were analyzed, where alI presented the same geometry, longitudinal and shear reinforcement and tends as variants the strength compression of the concrete, the presence or not of fibers of steel and the loading type that the beam was submitted (normal or inverted). The results obtained in the rehearsals, they allowed to analyze the behavior to the shear of each beam and also to quantify portion of contribution of the concrete (V c), in the strength shear, with the addition of fibers or with reverse loading
