Title: Effect of Range of Stress on Fatigue Strength of Plain Concrete Beams*

Abstract:From the results of tests of 175 plain concrete beams subjected to repeated flexural loading, it was found that plain concrete exhibits no fatigue limit when subjected to loads which produce no reversals of stress. Fatigue strengths at ten million repetitions of stress were determined for each of the several ranges of stress investigated, and these strengths were found to be dependent on the range of stress to which the specimens were subjected. The test results are in good agreement with previous investigations insofar as valid comparisons may be made. The need for additional research is, however, most apparent; the results obtained from this investigation do not permit the definition of the fatigue behavior of plain concrete subjected to reversals of stress, nor do they permit a valid description of the process by which fatigue failures occur.
