Abstract

In through truss bridges, severe corrosion damages have been observed at the diagonal members in boundary with concrete slab. The similar structural details are also used at boundary of web and flange in corrugated steel web PC bridges. In the future, the similar type of corrosion damages with the truss bridges seems to occur in the PC bridges. In this study, in order to clarify the corrosion behavior for the steel structural members in boundary with concrete, accelerated exposure tests were carried out on model specimens. And classification of the corrosion characteristics and the corrosion regions were analyzed using variograms and regression trees. As the result, corrosion behaviors at boundary and general corrosion region and that of anode region were clarified. Quantitative evaluation and estimation methods for corrosion behaviors in boundary with concrete of the steel members were also proposed.
