Abstract
A structure evaluation system includes a plurality of sensors and an evaluator. The plurality of sensors detect elastic waves generated in prestressed concrete in which a prestressed concrete steel material is internally provided. The evaluator evaluates a breakage of the prestressed concrete steel material based on elastic waves detected for a second period, which is a period after the elapse of a first period from a point in time when a magnitude of the elastic waves detected by the plurality of sensors is greater than or equal to a threshold value.
