摘要： The present invention relates to a structural damage detection method for detecting damage of a structure. The method comprises scanning the surface of the structure with a tapper tapping with a tapping force at a predetermined frequency band while scanning; measuring the response signals transmitted from the surface of the structure; transforming the measured signals to acquire the signal spectrum at each position of the structure surface; intercepting from the signal spectrum a spectrum envelope; calculating a damage indicator at each position of the structure surface; and determining a position where the damage indicator changes abruptly as a position of structural damage. The present invention further relates to a structural damage detection system utilizing the structural damage detection method and a structural damage detection device for use therein.
