Acoustic Emission to Predict Failure in a Finger-type Bridge Expansion Joint Model
Acoustic Emission (AE), a Nondestructive Testing technique, was used to monitor a very low-cycle load test on a steel and concrete finger-type bridge expansion joint model. Eight specimens were loaded near their ultimate capacity. Two specimens fatigued, and six specimens were forced to fail after a determined number of load-unload cycles. Counts (C) and Counts/Event (C/E) at the maximum load of the cycle were the investigated AE parameters. For six of the eight specimens, C/100 and C/E did not simultaneously attain or exceed values of 20.0 and 33.0, respectively, until failure occurred. It is hoped that with these quantitative results a standard can be established with the aid of future research for the use of AE to evaluate the structural integrity of bridge expansion joints. Recommendations for further research in the area of Acoustic Emission applied to a concrete and steel bridge expansion joint specimen are also presented.
