摘要：

This paper brief introduces the basic methods of structural damage detection at present; main introduces the method of structural damage detection by using vibration response. In the method of structural vibration response, the key to structural damage detection is characteristic extracting for vibration signals. How to effectively discern them from a large number of vibration signals. This paper analyses and deals with the vibration signals by using wavelet transform, including application of wavelet transform analysis in filer and reduction of noise and structural damage detection. The method has some practical values in structural damage detection.
