Abstract: According to an embodiment, a structure evaluation system includes a plurality of sensors, a position locator, a velocity calculator, and an evaluator. The sensors detect an elastic wave generated from a structure. The position locator derives a wave source distribution of the elastic waves generated from the structure, on the basis of the elastic waves. The velocity calculator derives a propagation velocity of the elastic wave generated from the structure, on the basis of the elastic waves. The evaluator evaluates the soundness of the structure on the basis of the wave source distribution and the propagation velocity of the elastic waves.

Abstract: According to one embodiment, a method is used for diagnosing a deterioration of a utility pole having at least one bolt and a plurality of holes provided for attaching the bolt. In the method, an impact is applied to the bolt. Elastic waves generated due to the impact are detected by a sensor shaped like a bolt. The sensor is attached to at least one of the holes. A propagation situation of the elastic waves in the utility pole is derived, based on the elastic waves detected, and each position of the bolt and the sensor.

Abstract: According to an embodiment, a structure evaluation system includes a plurality of AE sensors, a signal processor, a position locator, and an evaluator. The AE sensors detect an elastic wave generated from a structure. The signal processor performs signal processing on the elastic wave detected by the AE sensors and outputs an AE signal including information on the elastic wave. The position locator derives a source distribution indicating the distribution of sources of the elastic wave generated in the structure, using an AE signal caused by an impact on the structure. The evaluator evaluates a state of deterioration of a predetermined region of the structure from a density of the sources of the elastic wave obtained on the basis of the source distribution.
