This paper proposes a damage identification approach for tower structures based on the dynamic response information expansion This approach is to identify damage Positions of the tower structure by adopting wavelet transformation, which requires dynamic response information. However, it is noted that Gibbs phenomenon causes signal singularity at the end of identification range and resists the damage identification on the boundary and in the symmetry area of structures In this paper, the damage identification region of a tower structure is expanded to full structure height based on the effective continuation of dynamic response information, especially in the top and bottom of a tower, by eliminating Gibbs phenomenon The analysis results obtained show that this approach is effective, and reliable to structure damage identification.
