A minimum reinforcement ratio is an important factor to prevent a brittle failure for RC flexural members. In this paper, a parametric study of minimum reinforcement ratio is performed according to concrete strength, steel yield strength and cover depth ratio for each design provisions. A minimum reinforcement ratio using a stress-strain model is suggested. And results show that this mode is able to reflect material strength and cross-section properties properly.
