Research on Longitudinal Reinforcement Ratio of Reinforced Concrete Rectangular Section Single-Reinforced Beam

Based on the cost of concrete and longitudinal reinforcement of reinforced concrete rectangular section single-reinforced Beam, the authors take as the variable the reinforcement ratio and the valid height of the rectangular section, and then derive the economical reinforcement ratio and planned height for the reinforced concrete rectangular section single-reinforced Beam. The research result has important practical meanings for reinforced concrete rectangular section single-reinforced beam.
