Stage: PROBLEM TO BE SOLVED: To provide a corrosion diagnosis method for making corrosion diagnosis that reflects changes in a corrosion state of a steel structure.SOLUTION: A corrosion diagnosis method includes the steps of: measuring and recording a corrosion amount of a steel structure using an electric resistance type corrosion sensor attached to the steel structure; and diagnosing a corrosion state of the steel structure on the basis of the corrosion amount of the steel structure. The step of diagnosing a corrosion state includes the steps of: determining a reference time point that is a time point subsequent to a measurement start time point and that is a time point prior to a diagnosis time point; and calculating a corrosion prediction formula from a relationship between lapsed time in an evaluation object period and a corrosion amount, where a period from the reference time point to the diagnosis time point is considered to be the evaluation object period.SELECTED DRAWING: Figure 5 (Grant)
