Abstract
Corrosion is the major cause of deterioration of steel bridges, and corrosion damages seriously affect on the durability of steel bridges. So, corrosion damage must be carefully evaluated. At, present, however, there are no established means of evaluating the extent and effects of bridge corrosion. In this study, first of all, corrosion characteristics in steel bridge members are discussed. Amount of corrosion informations concerned with the types of corrosion found, locations of corrosion on bridge elements, and environmental effects on the structure in existing steel bridges were gathered and estimated. From this investigation, we are trying to make, so to says, corrosion maps of each types of steel bridges. Secondly, non-destructive techniques of adequate corrosion inspection are described.
