 Structural health monitoring, SHM, is an important part of maintaining bridges in areas with high seismic activity. This project used piezoelectric ceramics, PZTs, to monitor a reinforced concrete, RC, bridge column subjected to pseudodynamic loading. The PZTs were able to detect changes in the structure's health due to the presence of cracks, which reduced the amount of energy transmitted through the structure. A wavelet packet-based structural damage index was developed to measure the severity of the damage and detect the opening and closing of cracks. The experimental results confirmed the effectiveness of the PZTs in monitoring the RC column's health, under pseudodynamic loading. Additionally, the local structural damage indices showed promise in reporting the cyclic crack open-close phenomenon.
