Precise Vibration-Based Damage Localization in 3D Structures Consisting of 1D Elements: Single vs Multiple Response Measurements

Abstract : The goal of this study is twofold: (i) the refinement of the advanced Functional Model Based Method (FMBM), which through a detailed representation of 3D structures consisting of 1D elements achieves precise damage localization based on single or multiple vibration responses and, (ii) the comparison of the methodÕs effectiveness based on single and multiple response measurements. The refined method is equipped with modified ARX type Functional Models - Vector Functionally Pooled Vector AutoRegressive with eXogenous excitation (VFP-VARX) models - for the simultaneous exploitation of multiple responses and a proper optimization framework based on which the precise estimation of the damage coordinates upon the 3D structural topology under study is accomplished. The methodÕs effectiveness and the comparison between the use of single or multiple response signals are experimentally assessed via numerous damage cases in a 3D truss structure.
