Abstract

This paper proposes a practical method for determining the most economical steel ratio in RC flexural members. The costs of individual material and labor are considered. Then, an equation for determining the optimal steel ratio is proposes. It was found that a relevant steel ratio is recommended to be 0.95~1.0% for designing singly reinforced rectangular beam.
