### Minimum and Maximum Reinforcement Ratio in Different

Nov 20, 2020· The maximum reinforcement ratio is the largest steel area that can be put into concrete members like columns and beam. In a reinforced concrete beam, the provision of extra reinforcement above the maximum reinforcement ratio would not be beneficial since the concrete would get crushed before the full strength of steel is used.
