For members not supporting deflection sensitive slements aci table 9.5(a) provides deemed-to-satisfy provisions consisting of limiting span/depth ratios.these ratios are based on past experience and are applicable to normal types of construction.members conforming to these span/depth ratios are considered to have sufficient stiffness to prevent allowable deflections being exceeded. For normal weight concrete and grade 60 reinforcement the minimum thicknesses specified are given in table 3-4.for grade 40 reinforcement,the tabulated values are multiplied by the factor
R40
For lightweight concrete,the tabulated calues are multiplied by the factor
For other situations,where deflections have to be computed,consideration must be given to both short-term and long-term deflections.factors affecting the magnitude of deflections include:
An increase in restraint at the support reduces deflections
