Remote structural health monitoring of a FRP composite bridge
Increasing use of fiber reinforced composite material systems as primary structural members under severe operating conditions has raised the fact that there is still a lack of information related to design criteria, durability, and long-term response of such structures. In an attempt to address these problems a project was initiated in California focused on the installation of a composite bridge system on a major state highway. The fast-growing Internet technologies enabled the remote real-time monitoring of such a bridge and a scheme was developed using wireless technology to monitor the structural and material response. The data collected by a complete array of sensors are transmitted wirelessly and processed remotely on a server at UCSD. Computer-based automated analysis algorithms routinely process the incoming data and structural irregularities are determined based on pre-defined thresholds. The results are made available to engineers at California Department of Transportation via Web-based interface. Based on the results, appropriate action may be authorized for maintenance or emergency response. It is expected that this system will not only give engineers a valuable tool in monitoring and maintaining the current bridge, but also provide critical information of the durability, design criteria and long-term response of FRP composite structural components.
