Abstract:  Building codes and standards include methods and provisions for deflection control and determining minimum thickness of slabs and beams, also determine the immediate and long or timedependent deflection. The ACI code depth-span limitations tabulated for normal weight concrete and specified yield strength of steel. For other values of steel yield strength and lightweight concrete correction factors are provided. In this study, correction factors are suggested to include the effect of tensile reinforcement on the depth-span ratio in addition to the ACI code correction factors.
