Abstract:

In preparation for a large rehabilitation project on the Anthony Wayne Bridge (AWB), the Ohio Department of ; Transportation has expressed interest in evaluating monitoring and protection strategies which may extend the life ; of the AWB. This study was proposed and performed in line with this goal. Corrosion of the main cable was ; identified as the driving mechanism for the aging of suspension bridges. Experiments were performed in order to ; determine whether or not the existing acoustic monitoring system on the AWB could be used to readily identify ; active corrosion. Results from laboratory testing show that use of acoustic emission to detect corrosion is possible ; and promising; however, field experiments indicate that additional tests are needed to determine the practicality of ; identifying corrosion in the field. The upcoming bridge closure will provide a great opportunity for researchers to ; more closely examine this possibility. In addition, this report includes literature investigation into other state-of-theart ; corrosion monitoring and protection strategies including an internal sensor array, the magnetic main flux method ; for wire inspection, and cable dehumidification.
