Abstract
Advanced composite materials are widely recognized to be an effective material for the strengthening of structures subjected to seismic events. These materials are also being investigated as a potential rehabilitation technique to increase the live-load capacity of a bridge. While there are benefits to this technique, there are limitations as well, such as a lack of long-term performance data. Performance is taken here to include serviceability, reliability and durability. This paper will demonstrate how a structural health monitoring system can be utilized to determine measures of performance for a bridge rehabilitated using advanced composite materials. First, the theoretical framework of the health monitoring system will be developed. Next, the philosophy and design of the composite rehabilitation will be described. As part of the monitoring process, the bridge will be tested prior to beginning the rehabilitation work to verify the base line condition. After the rehabilitation work is completed, data will be collected on a periodic basis and the results evaluated to determine the performance of the bridge was improved.
