Abstract

近年数多くの耐候性鋼橋が建設されているが,その実態について体系的な調査は行われておらず,鋼橋における耐候性鋼材のパフォ-マンスが十分に把握されているとは言い難い.そこで,九州橋梁・構造工学研究会(KABSE)に設置された「九州・山口地区における耐候性鋼橋の調査・研究分科会」の活動の一環として,同地区の耐候性鋼橋300橋以上を対象に実態調査を行った.ここでは,その調査結果,ならびにさび状況と調査項目との関連性の検討結果を報告する.

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.
