In recent years, the structure made of weathering steel has been paid attention concerning the life cycle cost. The Japan guideline describes the rules of the construction for the weathering steel bridge that the weathering steel is applicable in the region which is more than 5km from the coast of the Japan Sea. Many weathering steel bridges have been constructed in Shimane. However, the performance of the weathering steel in those bridges is not well traced.
The authors conducted the field study of performance on the weathering steels in Shimane. This paper is reported the results of our investigation into the corrosion condition from the point of view rust development.
