Webcrushing failure in beams is a brittle failure mode as it typically occurs suddenly without warning. In order to ensure ductile shear behaviour, shear strength is limited by the maximum strut capacity equation (webcrushing equation) to prevent the crushing of concrete before the yielding of shear reinforcement.
