Study on Sensitivity of PZT Signatures for Damage Detection in RC Columns—A Numerical Study

Yedlapati, Venkat Shivaram / Alapati, Mallika

Structural health monitoring using EMI techniques have gained attention of the researchers in the past two decades. Damage detection in RC structural components in the form of cracks is important as it reduces the stiffness of structural members. Also, the occurrence of cracks in the near vicinity of the critical locations is a major issue which has to be addressed at the time of initial crack propagation. PZT sensors are effective in identifying the incipient damages locally. In the present paper, conductance signatures (real part of EMI signatures) are extracted from the smart RC column in healthy and damaged conditions (in the form of cracks) under different frequency ranges, i.e. 0–10 kHz and 0–300 kHz, and found that there is significant change in the conductance signatures by which the damage location and severity can be identified. The method also found to be effective in identifying the incipient damages in a low-frequency range of 0–10 kHz with well-defined changes in the EMI signature patterns.
