Application of wavelet analysis to structural damage identification

For comfirming the validity and applicability of structural damage identification methods,wavelet analysis is used to structure damage detection.On the basis of the theory of wavelet analysis,three methods of structural damage identification,which include time-domain response based methods,space-domain response based methods and other methods combined with wavelet analysis,are discussed in detail.Subsequently,application state,application range and existent problems of diversified methods are analyzed.Through comparison with other methods,it is obvious that the method taking wavelet analysis into structural damage identification is promising.Finally,five advices to the further research direction are put forward in this paper.
