Abstract
![CDATA[This paper presents a novel technique to detect the delamination between steel bars and concrete in RC structures using wavelet packet analysis. A damage index is constructed based on the wavelet packet component energy change. The experimental study is carried out on a concrete slab with different debonding damages between steel bars and concrete. The piezoelectric components are mounted on steel bars that are embedded in the slab as actuators and sensors. The results show that the wavelet packet component energy is sensitive to the debonding damage and could be a good damage indicator.]]
