To ensure the safety of weathering steel structures, it is important to evaluate the time-dependent corrosion behavior. Thus, progress and effect of corrosion damage on weathering steel members should be evaluated, but predicted corrosion depth do not go far enough until now, which is affected by the corrosion environment. In this study, the corrosion resistant of weathering steel was examined to quantifiably investigate and compare the corrosion depth of carbon and weathering steel.
