Acoustic Emission Monitoring of a Fracture-Critical Bridge

Status:  Complete
Report Date:  03/21/2014

Summary:

Researchers tested and optimized an acoustic emission bridge health monitoring system to sense cracking in fracture-critical steel bridges by using the system to collect data on the Cedar Avenue Bridge in Burnsville, Minnesota. The final report provides a framework for selecting appropriate acoustic emission equipment and formulating effective data processing methods for assessing the formation and growth of cracks in these bridges.
