Paper Abstract

In this paper, we present a damage monitoring method to detect and track the evolution of structural damages based on the measurements acquired by vibratory gyroscopes. We propose a modal flexibility-based damage index that quantifies the local bending flexibility of the beam structures by conducting virtual local loading tests. We use vibratory gyroscopes to measure the angular mode shapes which are necessary to assess the proposed damage index. A time-frequency analysis-based simple scheme is developed to identify the time-varying mode shapes to detect and track the evolution of the damage index. Experimental results show that the proposed monitoring method is capable to indicate the location of the damages as well as the time when they occur.
