Abstract

According to one embodiment, a structure evaluation system includes a plurality of sensors, an acquirer, a calculator, and an evaluator. The plurality of sensors detects elastic waves generated from the structure. The acquirer acquires detection information for an evaluation target period in which information on at least an amplitude of each elastic wave detected by each of the plurality of sensors is associated with time information on the time when each elastic wave is detected. The calculator calculates an evaluation value, which is a slope of an amplitude scale-based frequency distribution of elastic waves, every predetermined period based on the acquired detection information for the evaluation target period. The evaluator evaluates a deterioration state of the structure based on the time-series data of each evaluation value calculated every predetermined period.
