Detection of Flaws in Reinforcing Steel in Prestressed Concrete Bridge Members: Signal Enhancement and Interpretation
The long range objective of the research summarized in this report is the development of a practical nondestructive evaluation (NDE) method for detecting deterioration in the reinforcement of prestressed concrete bridge structural members in situ. Prior development of the Magnetic Field Disturbance (MFD) inspection system under contract No. DOT-FH-11-8999 is summarized and examples are given which show the nature of the signal discrimination and interpretation problems to be solved if the full potential of the MFD method is to be realized. The technical approach to signal enhancement and interpretation is outlined, and the results obtained from laboratory investigation of sensor arrays and digital signal processing techniques are presented. Subsequent modifications to the existing MFD to incorporate a sensor array and signal processing capability are described.
