This report is a summary of the essential findings of a study of the fatigue strength of high yield reinforcing bars (generally Grades 60 and 75). A statistically valid experiment was performed employing 353 fatigue tests on concrete beams, each containing one reinforcement bar. Test results were entered in an over-all multiple linear regression analysis. The major effects studied were stress range, minimum stress, bar diameter, type of specimen, grade of bar, and bar geometry. On the basis of the observed behavior, a fatigue design provision was developed for deformed reinforcing bars, suggesting a limitation on the service load stress range.
