Abstract

In the authors' previous study, to investigate the corrosion behavior for the steel members in boundary with concrete, accelerated exposure tests were carried out on the model specimens. In addition, the method of numerical simulations using referential spatial statistics was proposed to predict the time-dependent corroded surfaces corresponding to the service period in structures. Moreover, fatigue tests were carried out to investigate the fatigue behavior of corroded members. In this research, FE stress analyses were also performed to clarify the stress concentration factor at the various conditions of the corroded surface. From the experimental and analytical results, quantitative evaluation and prediction methods for time-dependent stress concentration factor and fatigue life of the corroded members were proposed.
