Identifying location and severity of multiple cracks in reinforced concrete cantilever beams using modal and wavelet analysis

In this paper, a method of multiple cracks detection in a cantilever reinforced concrete beam based on wavelet transform is presented. For this purpose, different damage scenarios in concrete beam were considered. Then, the four first mode shapes of undamaged and damaged beam using ABAQUS software w...

The estimated mode shapes of the beam are analyzed by the continuous and discrete wavelet transform (CWT & DWT) to detect the damage scenarios.
