Abstract
Sensitivity of damage detection for beam siructures with multiple damages is discussed. Mode shape of beam structures is estimated by strain response. The influence of damage on mode shape is shown by comparison between damaged beam and intact beam. Damages are detected from the mode shape. To detect position of the damage, continuous wavelet transform is applied to the difference in the mode shape. A peak of the wavelet transform become high with the increase of the damage level.
