Abstract: A structure evaluation apparatus has an acquisitor and an evaluator. The acquisitor acquires a distribution that represents a distribution of strength of a reflected wave obtained by an electromagnetic radar scan to a reinforced concrete which comprises concrete and a material other than concrete. The evaluator calculates similarity, with reference to a reference region including the material in the distribution, of other regions including the material than the reference region in the distribution.

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.

Abstract: According to one embodiment, a structure evaluation system includes an impact imparting unit, a plurality of sensors, a position locator, and an evaluator. The impact imparting unit applies impacts to a second region different from a first region of a structure to which traveling sections of a vehicle, which travels on the structure, apply impacts. The plurality of sensors detect elastic waves generated in the structure. The position locator locates a position of a source of the elastic waves on the basis of the elastic waves detected by each of the plurality of sensors. The evaluator evaluates a deterioration state of the structure on the basis of a position location result of the position locator.

Abstract: A state evaluation system includes a sensor, a filter, a signal processor, and an evaluator. The sensor detects elastic waves which are generated from industrial equipment in operation. The filter can pass elastic waves having frequency characteristics based on abrasion which is generated in the industrial equipment. The signal processor extracts a plurality of feature values using the elastic waves passing through the filter. The evaluator evaluates an abnormality of the industrial equipment on the basis of a combination of the extracted plurality of feature values.

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.
