A1
Abstract:
A diagnostic device 1 includes: a generation unit 2 that acquires, from a plurality of sensors 21 disposed in a structure 20, vibration information representing vibration which occurs in the structure 20, and uses the vibration information to generate characteristic vibration mode information representing a characteristic vibration mode shape; an occurrence rate calculation unit 3 that calculates the occurrence rate of a normal characteristic vibration mode shape on the basis of the number of times a vibration is applied to the structure 20, and the number of times the normal characteristic vibration mode shape is generated when a vibration is applied; and a diagnostic unit 4 that diagnoses the presence/absence of a repair/reinforcement effect on the structure on the basis of the occurrence rate and a reference value.
