An approximate simplified procedure is described for estimating the effective moment of inertia I, for beams, T-beams, or one-way slabs constructed of normal weight aggregate concrete or lightweight concrete, and reinforced with 40-80 ksi reinforcing bars. The results are compatible with Ie values obtained from Eq. (9-7) of ACI 318-77. The simplified equations do not require computations for moment of inertia of the cracked section Icr, nor the reinforcing requirements initially. Also described is a simplified procedure for establishing minimum member depth so that deflection computations to ascertain serviceability may be avoided when designing the majority of one-way members
