Damage localization in beams based on the analysis of modal parameters

This paper presents a two-step method for damage localization in beams by combining natural frequencies and mode shapes. The general locations of the are first identified from an indicator developed using relative frequency change (RNFC) curves values RNFCs. A curvature-mode-shape-based is then utilized to determine specific location second step. proposed verified detecting simulated simply-supported beam. agrees well with actual location. strategy fast accurate based on shapes main novelty paper.
