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 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.

Abstract: According to one embodiment, a structure evaluation system of the embodiments includes a plurality of sensors, a position locator, and an evaluator. The plurality of sensors detect elastic waves. The position locator locates elastic wave sources on the basis of a plurality of elastic waves detected by each of the plurality of sensors. The evaluator evaluates a deterioration state of a structure in accordance with a presence or absence of a sensor and an elastic wave source distribution which shows a position of the elastic wave sources obtained on the basis of a result of locating of the elastic wave sources.
