An Artificial Filter Bank (AFB) for Structural Health Monitoring of Civil Structures – Part2: An Implementation and Evaluation of the AFB

For the evaluation of the developed AFB, a real time dynamic response experiment was performed on a cable-stayed bridge model, and the response of the cable-stayed bridge model was measured using both the traditional wired system and the developed AFB-based USMS. The experiment results showed that the compressed dynamic response acquired by the AFB-based USMS matched significantly with that of the traditional wired system while still carrying sufficient modal information of the cable-stayed bridge. Therefore, the developed AFB was able to reconstruct or resample the dynamic response wholly from the compressed response signal, and it can be applied as a new kind of measurement system for a WSN-based structural health monitoring system that secures both economy and efficiency.
