According to the AASHTO LRFD Bridge Design Specifications, minimum reinforcement provisions are intended to reduce the probability of brittle failure by providing Minimum and Maximum Reinforcement Ratios for Flexural flexural reinforcementMaximum Flexural Reinforcement by 2008 MSJC Code. The 2008 MSJC Code has a maximum reinforcement requirement (Sec. 3.3.3.5) that is intended to ensure ductile behavior over a range of axial loads. As compressive axial load increases, the maximum permissible reinforcement Minimum and Maximum Reinforcement Ratio in Different flexural reinforcement1. Minimum Reinforcement Ratio in Beams. In reinforced concrete beams, if the cracked sections flexural strength is lower than the moment that produced cracking of the previously uncracked section, then the beam would fail upon the formation of the first flexural crack, without showing any distress.
