Repeated loading of reinforced concrete beams

Various low frequency load histories were applied to singly reinforced concrete beams. All beams were under reinforced to give a load deflection curve with a distinct horizontal yield plateau. Beams were simply supported with concentrated loads at one third points. Maximum and minimum loads of approximately 90% and 20% respectively of the beam's yield load were applied in a particular load history. Incremental deflection resulted from the yield of reinforcement at flexural cracks and also from bond slip. In general the stiffness of the beams increased with repeated loading. No significant reduction was observed in the yield and ultimate loads of the beams as a result of the repeated loading (a).
