PERFORMANCE OF WEATHERING STEEL IN BRIDGES IN KYUSHU-YAMAGUCHI REGION

Abstract

Many weathering steel bridges have been constructed in recent years. However, the performance of the steel in those bridges is not well traced and so little known. Against this background, “Committee on the Performance of Weathering Steel Bridges in Kyushu-Yamaguchi Region” in Kyushu Association for Bridge and Structural Engineering (KABSE), conducted the filed study of performance of weathering steel in bridges in the region. This paper describes the result of this study, based on which the factors that may influence the rust development are also discussed.
