  • Patent number: 11874292
    Abstract: A diagnostic method includes the following steps. A step of detecting values of an acceleration of a vibration of a building floor. A step of calculating vibration information related to the vibration of the building floor based on a detection signal. The vibration information includes frequencies and magnitudes of the vibration. A step of performing a vibration diagnosis of a structural body of a diagnosis model based on the first vibration information, an index related to a vibration of the structural body, and information on a display device. The index is a standard of the vibration allowed for the structural body. The displayed information identifies a plurality of supports that are candidates for a first support installed between the building floor and the structural body. A step of outputting a first diagnosis result of the vibration diagnosis to the display device.
