Evaluation of Corrosiveness of Various Parts of Weathering Steel Bridges

摘要

For the method to evaluate the corrosiveness of various parts of weathering steel bridges quantitatively and prospect their lives, a new monitoring method was examined. ACM sensors were attached to various parts of the experimental bridge exposed to a coastal environment, and their output, galvanic current, was continuously recorded for 1 year. The output of the ACM sensors characterized the corrosiveness of various parts and was strongly associated with the thickness loss of specimens of JIS SMA placed at the same positions as the sensors.
