摘要：
Several Db (Daubechies I) family wavelet functions are chosen in the study of a numerical model on four-story steel frame structure by using wavelet probabilistic neural network methods, and the effect of different wavelet functions on structural damage identification is discussed. This study shows that the wavelet function with good regularity and great vanishing moments is the best one in structural damage identification.
