Health monitoring of interlocking reinforced concrete columns under seismic excitation (2)

Objective: To further verify the effectiveness of the proposed piezoceramic-based approach for the structural health monitoring of reinforced interlocking concrete columns subjected to shake table excitations.
Experimental setup: reinforced concrete (RC) interlocking column, shake table, dSpace data acquisition system
Method: Smart aggregate-based health monitoring approach, wavelet packet analysis
Conclusion: The structural health monitoring results show that transmitted wave attenuated at different frequency ranges and the attenuation level is proportional to the damage severity. An attenuation matrix is developed based on the frequency responses of wave propagation. From the experimental results, it is shown that the high frequency signals are sensitive in detecting damages and extracting damage features.
