Abstract

One of the methods for damage detection is dynamic methods based on the signal, which can be used to detect damage in the structures through signal processing. In this study, wavelet transform is used in order to determine the location and extent of the damage in steel plate shear walls so that the mode shape of modal analysis is decomposed as the input signal by wavelet transform and in the case of damage, it is possible to identify its accurate location. As a result, by using this transform without information of healthy structure, the possible damage scenarios that occur in the structure can be detected through disturbances which are created in the signal or the mode shapes of steel plate shear walls.
