Abstract
A full-scale highway bridge, in the process of being demolished and replaced, was monitored using vibrational techniques. The bottom of the flange and web of one fascia girder were incrementally cut. Vibrational monitoring during the passage of a test vehicle was used to demonstrate that the vibrational signature of a bridge will change when a major defect occurs. Included in this paper is a discussion of how vibrational studies have been used in the evaluation of bridges.
