Effect of Load Variations on the Flexural Fatigue Strength of Plain Concrete
Reported here are the results of a laboratory study of the fatigue characteristics of plain concrete. The primary goal was to evaluate the effect of load variations on the fatigue life; to determine whether the Miner hypothesis adequately represents cumulative damage. To obtain the necessary data, 6 x 6 x 64-inch plain concrete beams were subjected to two levels of repetitive flexural loads, until failure occurred. The magnitude and direction of the change, and the number of cycles applied at the first stress level were varied. The results of these tests were evaluated in comparison with the data from monotonic fatigue tests which were used to establish the basic S/N relationship for this study. As a prelude to the report, a state-of-the-art discussion has been given covering previous research on the fatigue characteristics of plain concrete. (Author Modified Abstract)
