In the authors' previous study, to investigate the time-dependent corrosion behavior for the steel structural members in boundary with concrete, accelerated exposure tests were carried out on model specimens. In addition, numerical simulations using referential spatial statistics were also performed on the models to predict the corroded surfaces corresponding to the service period. In this research, fatigue tests were carried out to quantitatively clarify the fatigue behavior of corroded structural members in boundary with concrete. In the fatigue tests, specimens after accelerated exposure tests were used. Finite element stress analyses were also performed on the models based on the corroded specimens to investigate the stress concentration at the corrosion pit occurred in the boundary. From the experimental and analytical results, fatigue behaviors of corroded steel members in boundary with concrete were clarified. Quantitative evaluation and prediction methods for time-dependent stress concentration factor and fatigue life of the corroded members were also proposed.
