APPLICATION OF THE GARD/FHWA ACOUSTIC EMISSION WELD MONITOR (AEWM) TO HIGHWAY BRIDGE STRUCTURAL MONITORING

A unique acoustic emission monitoring system originally developed for in-process weld monitoring has been used to monitor fatigue crack growth in a highway bridge during normal traffic loading. The system was able to clearly and reliably detect the presence of fatigue cracks that were adjacent to a row of bolts. The results of the brief experiment show that the signal processing used in this AE system may allow drastic improvements in the ability of acoustic emission to reliably detect propagating bridge
