内容記述タイプ Abstract
内容記述 A change of modal characteristics can indicate structural damage. Based on changes in Power Spectral Density (PSD), this paper proposes a damage identification technique that detects damage and its location. The method is applied to a finite element model of a three span steel bridge with a concrete deck. Several damage scenarios were introduced to a main girder of the bridge. The method determined the exact damage location. In addition, the results illustrate that changes in the PSD curvature can be a useful tool for continuous monitoring of structural integrity using ambient vibration data. Furthermore, changes in the PSD curvature do not require a very fine grid of measurements to detect and locate damage effectively.
