Damage Identification of Cantilevered Beam Based on Multi-Resolution Analysis

Abstract:

As a derivative parameter of the structural displacement mode, damage factor matrix was adopted to investigate the detection of structural crack location and damage. A methodological strategy by combination of the damage factor matrix and the wavelet multi-resolution analysis is presented in the paper, in order to identify structural damages of the cantilevered beam. The results show that damage can be identified by the damage factor matrix and the wavelet multi-resolution analysis, and the damage degree can be estimated by damage frequency band energy of the wavelet analysis. A reference to damage identification in current structure engineering is provided.
