The purpose of this paper is to evaluate the effect confinement on ultimate drift ratio of reinforced concrete beam specimens using normal concrete. All beam specimens were tested under cyclic loading. The measured compressive strength of the concrete is in the range of 25 – 41.8 MPa, longitudinal reinforcement yield strength is in the range 350 – 570 MPa and transverse reinforcement yield strength is in the range 275 –570 MPa. Test parameters include s/d b ratio, ρ t , and V s ,a/M n ratio. The results showed that V s ,a/M n ratio have a significant effect on the ultimate drift ratio. Increase the nominal shear strength by confinement leads to an increase of ultimate drift ratio. In other hands, spacing of transverse reinforcement not exceeding 8d b can achieve minimum 3.00% ultimate drift ratio.
