In this study, in order to perform more efficiently safety design and integrity assessment of structural members, the relational database system on the fatigue strength of steels was constructed. Fatigue strength database contained 343 S-N curves for 39 kinds of the steels and was developed using MS-SQL 2000. Furthermore, the application program for reliability analysis was developed to consider variation of applied stress and fatigue strength. This program consists of 5 modules: search condition, evaluation of P-S-N curve, probabilistic characteristics of fatigue strength and applied stress history, and reliability analysis with strength-stress interference model.
