Abstract
A steel deck bridge evaluation device includes a processor configured to acquire reflected response data relating to a reflected response to an electromagnetic wave irradiated through a surface of a deck in a depth direction of the deck, remove a first frequency component obtained by reflection of the electromagnetic wave at a surface of the deck and a second frequency component obtained by reflection of the electromagnetic wave at a steel deck from a reflected response frequency distribution of the reflected response expressing the reflected response data, and evaluate damage to or deterioration of the deck using a peak measurement value that is a peak value of a frequency component level corresponding to a specific frequency or higher, in the reflected response frequency distribution from which the first frequency component and the second frequency component have been removed.
