A deflection of a RC structure increases when sustained loads are applied in it. In this paper, a parametric study of long-term deflection was performed according to concrete strength, creep coefficient and ratio of sustained load for each design provisions. Results show that a long-term deflection in KSCDC is able to apply an effect of creep using an effective modulus of elasticity.
