N2 - Severe localized corrosion damages have been observed at the steel members in boundary with concrete on some steel structures. In our previous study, accelerated exposure tests and numerical simulations using referential spatial statistics were carried out to investigate the corrosion behavior for the steel structural members in boundary with concrete. In this research, fatigue tests were carried out on corroded specimens by accelerated exposure tests to investigate the fatigue behavior of corroded structural members in boundary with concrete. FE stress analyses were also performed on the models of the corroded surfaces of the specimens and the simulated corrosion surfaces to investigate the stress concentration at the corrosion pit in the vicinity of the boundary. The experimental and analytical results clarified the fatigue behaviors of corroded steel plates in boundary with concrete. The method for evaluating the fatigue life of corroded steel members was also proposed.
