    The ACI 318-19 has also determined the maximum reinforcement ratio p max that can be put into a doubly reinforced concrete beam to ensure steel bars in the beams tension zone yield. Therefore the p max ensures that the beam fails by tensile yielding of steel instead of crushing of concrete which is sudden and undesirable.
