DAMAGE DETECTION APPARATUS, METHOD, AND PROGRAM

The present invention provides a damage detection apparatus, a damage detection method, and a damage detection program that can detect damage in a support by measuring vibration of a supported object. The damage detection apparatus that detects damage in a structure including a supported object and a support according to one example embodiment of the present invention includes a dominant frequency acquisition unit that acquires a dominant frequency from vibration information at a plurality of points on the supported object; a rigid body vibration identification unit that identifies rigid body vibration information on the structure from the acquired dominant frequency; and a damage determination unit that determines damage in the support based on the identified rigid body vibration information.
