Achieving the critical steel ratio in construction joints or weak planes of concrete structures ensures that the concrete, not the steel reinforcement, fails first under tension. This is crucial because concrete failure in tension results in multiple, smaller cracks, which are preferable to the few wide cracks that would occur if the steel reinforcement yielded first. By prioritizing concrete failure, the structure maintains its overall integrity and avoids the concentration of stresses in fewer, larger cracks.
