WAVELET-BASED ACTIVE SENSING TECHNIQUE FOR DELAMINATION DETECTION IN RC STRUCTURES
The study is to present a wavelet-based active sensing technique to detect the delamination between the steel bars and concrete in the reinforced concrete structures using the guided waves. The piezoelectric components are mounted on reinforcing bars that embedded in RC structures as sensors and actuators to generate the guided wave, which is sensitive to the delamination between the steel bars and concrete. The guided wave is analysed by the Morlet wavelet transform as a basis to construct the damage sensitive features. The original input signal is reconstructed using waveletbased signal processing. Damage can be detected by examining the distortion of the time reversibility.The experimental validation is carried out on a concrete slab with different debonds.
