Acoustic Emission Monitoring of Field Bridges in Louisiana

Acoustic emission monitoring of bridge structures is not a new vista. Yet, even today the method has not been fully exploited in bridge monitoring as most evaluations are only qualitative and other NDT methods like ultrasonic have to be used to quantify the results observed from global monitoring. Though numerous quantitative methods have been proposed, they have not yet developed to be useful for actual field test use. Here an attempt is made to use the intensity analysis technique of damage quantification to two genres of bridges: a prestressed concrete slab-on-girder bridge and a steel bridge with concrete deck. Although there were limitations with the number and type of sensors used, essentially a lot of good information was collected and useful inferences are made that may help to better diagnose the health of bridges monitored in the future using acoustic emission.
