Abstract

In order to effectively identify the location and extent of structural damage, a two-stage damage identification method, ACO algorithm and wavelet theory were presented. First, the curvature mode of structure with damage was obtained with finite element analysis. The curvature modes were analyzed using continuous wavelet transform by Mexh wavelet on multiple scales, and the location of the damage could be identified by the maximum of the wavelet coefficients. Then, the objective function was established by the frequency and modal shape. ACO algorithm was used to solve constrained optimization problems, to identify the degree of structure damage. Through the analysis to a three-span continuous beam, the results show that the ACO algorithm and wavelet theory can effectively identify the damage location and damage degree of the structure.
