A library system has been developed for the acquisition, compilation and storage of information relating to the fatigue behavior of metal members and structures. Test data obtained from the various information sources are stored on both data sheets (for individual examination), and on standard computer punch cards. A computer program has been developed to sort the data into sets satisfying certain stipulated specimen types and loading conditions. A 'best-fit' S-N curve for each specified data set is then established using a least squares error of estimate and correlation coefficient of the regression line, and the lower tolerance limits for 99 percent survival at 50 percent and 95 percent confidence levels. The data and S-N curve are visually displayed using a CALCOMP plotter printout. Information obtained from an analysis of the data in the Fatigue Data Bank for several selected details indicates that the current AASHO bridge design specification provisions, for these details, do not provide consistent correlations nor properly model the fatigue behavior of the details as established by laboratory tests.
