Résumé / Abstract
Long-term structural health monitoring (SHM) of engineering structures is an excellent procedure for assessing and predicting damage occurrences. Monitoring continuously a structure means that large amounts of data will be collected and provided to the bridge owner for utilization. There is a risk that the amount of data becomes more important than the quality and interpretation of the data. Developing new metrics that use SHM information in a probabilistic approach when assessing the structural performance is, consequently, a great challenge. The objective of this paper is to use performance functions based on monitoring information that consider uncertainties and correlation in recorded measures. The proposed approach is applied to an existing bridge for which a long-term monitored program was performed by the Engineering Research Center for Advanced Technology for Large Structural Systems (ATLSS), at Lehigh University, Bethlehem, Pennsylvania.
