Experimental verification of the damage localization procedure based on modal filtering

Abstract

Modal filtering has numerous applications in the analysis of object dynamics. One possible use of this technique, recently presented in the literature, is damage detection. The method has several advantages but one major disadvantage — it does not provide any information about damage location. This article presents a solution that eliminates this drawback. The proposed method is tested first on a numerical example. Next, it is verified on the laboratory measurement data, and finally, it is applied to a real structure — a footbridge over a street in Krakow.
