A new structure damage identification method is proposed based on wavelet packet analysis of the time-domain response.Through decompositions of the time-domain responses of intact and damaged structures using the wavelet packet transformation, it is known that the distribution of the wavelet packet node energy of response will vary after the structure is damaged.
