  • Instrument for detecting hidden structural damage in multi-story buildings
    Patent number: 5526694
    Abstract: An electronic measuring instrument measures and records the acceleration frequency spectra of a multi-story building while it is excited by wind. Such frequency spectra are indicative, in part, of building structural stiffness. When a tramatic structural event occurs, such as an earthquake, an explosion, or a hurricane, changes in wind-excited frequency spectra are used to detect hidden structural damage to the building.
