• In order to use the corrosive protection characteristic of a weathering steel bridge effectively, it is very important to understand the corrosion factor and rust mechanism. In this paper, the relationship between rust level of weathering steel bridge and structural property, geographical data and meteorological factors was analyzed. From the results of Quantification Method 1, rust level is influenced by not only distance from shore but also rainy days and average temperature. Prediction of rust level using regression coefficients obtained from Quantification Method 1 was also carried out. Estimated rust level was suited well for the investigation results of bridges in Kyushu-Yamaguchi region.
