To address the limitations of curvature mode indicators in identifying minor structural damage, a method for structural damage identification that combines curvature mode and wavelet transform has been proposed. In this paper, ANSYS was used to establish a finite element model of the wooden beam before and after the damage and carry out modal analysis, and the curvature modes of the wooden beam before and after the damage was subjected to discrete wavelet transform to obtain the wavelet coefficient difference index. the damage location of the wooden beam was judged according to the peak of the wavelet coefficient difference mutation, and the damage degree of the wooden beam was estimated by fitting the relationship between the wavelet coefficient difference and the damage degree. The wooden beam test verified the index. The results show that the wavelet coefficient difference index can accurately identify the damaged location of wooden beams. The damage degree of wooden beams can be quantitatively estimated by fitting the relationship between the wavelet coefficient difference index and the damage degree. The research results provide a theoretical basis for wooden beam damage identification.
