Bridge Monitoring

This project proposes an approach to bridge structural monitoring that combines the advantages of a robust structural health monitoring paradigm with those of decentralizing the monitoring apparatus to fleets of vehicles that can continuously store or send data. The objective is to provide accurate, rapid, nearly continuous, and cost-effective assessments of several bridges. The new methodology envisions a set of moving vehicles equipped with sensors (which most of them already possess) able to capture the dynamic interaction between the vehicles and the bridge. As this interaction depends also on the modal characteristics of the bridge, the project hypothesizes that changes in the dynamic interaction can be inferred from damage-related features of the bridge. The methodology couples the sensing system to multi-resolution signal processing and pattern recognition algorithms to capture, locate, and classify variations in structural dynamic properties, e.g. resonant frequencies, mode shapes, or localized stiffness. The proposed approach can be considered as indirect, since it acquires information about the bridge from sensor-equipped vehicles moving over the bridge. This approach needs no installation of equipment on the bridge or any traffic control measurements, being highly distributed and mobile. A key aspect of this project is to assess different classification techniques for determining the presence or absence, and extent of damage.
