Description: This paper presents the effects of longitudinal tensile reinforcement ratio and shear span-depth ratio (a/d) on the minimum shear reinforcement in reinforced concrete beams. Twenty-six reinforced concrete (RC) beams having the minimum shear reinforcements required by ACI 318-05 were cast, instrumented, and tested. Although the minimum amount of shear reinforcement in the existing design codes (ACI 318-05, CSA A23.3-04, AIJ-99, and Eurocode 2) depend on neither the longitudinal tensile reinforcement ratio nor the a/d, the test results indicated that the reserve shear (shear strength of the beam with minimum amount of shear reinforcement/shear strength of the beam without shear reinforcement) of the tested beams increased as the longitudinal tensile reinforcement ratio increased, but decreased as the a/d increased.
