WebFor an RC beam initially reinforced with only longitudinal and transverse steel bars, when the diagonal shear crack occurs, the stirrups crossing the shear crack should be able to bear the shear load, avoiding diagonal tension failure. This kind of failure in non-corroded RC beams is usually avoided by prescribing the minimum amount of stirrups.
