Development of Acoustic Emission Evaluation Method for Repaired Prestressed Concrete Bridge Girders

Acoustic emission (AE) monitoring has proven to be a useful nondestructive testing tool in ordinary reinforced concrete beams. Over the past decade, however, the technique has also been used to test other concrete structures. It has been seen that acoustic emission monitoring can be used on in-service bridges to obtain knowledge regarding the structural integrity of individual components of the structure. In this report, acoustic emission testing was used to examine the structural integrity of four prestressed girders in an elevated portion of the I-565 highway in Huntsville, Alabama. The testing was performed to assess the evaluation criteria used for in-situ testing. The evaluation methods that were implemented were the NDIS-2421 evaluation criterion, the Signal Strength Moment (SSM) Ratio evaluation, and the Peak Cumulative Signal Strength (CSS) Ratio analysis. It was concluded that although the testing procedure provided results efficiently, the evaluation criteria should be adjusted for the testing of in-service prestressed concrete bridge girders.
