Describes experiments to investigate the effect of the rate of loading on the moment-curvature relation of prestressed concrete beams. It was found that the relation is dependent on the rate of loading, the steel ratio, and on the ratio of the effective depth to the over-all depth of the beam. The ultimate moments of under-reinforced sections tend to increase with increase in the rate of loading. In the case of over-reinforced sections, it seems that there is a rate of loading at which the ultimate moment is a minimum.
