Learn how to find the required amount of steel to carry the moment demand in a reinforced concrete beam. This video presents two different methods for estimating the steel area: a ballpark method, and a more exact stress ratio method. After introducing these principles, a full design example problem is shown. ACI 318-19 provisions are all satisfied for the minimum area of steel, bar spacing, and beam width.
