Outline of Final Research Achievements

The purpose of this research is to develop a simulator for predicting fatal corrosion damage at each part in steel structures. Spatial-temporal statistical corrosion model for coated steel members considering couples between corrosive environment and coating film deterioration was constructed by reflecting mechanism of coating film deterioration on established evaluation method of corrosive environment by author's previous study and time-dependent corrosion model for uncoated steel member. In addition to this, simulation method was also established by using the corrosion model.
