Nondestructive Testing of a Weld Repair on the I-65 Bridge Over the Ohio River at Louisville

Nondestructive evaluation methods were applied to verify the structural integrity of a fracture critical structural member on the I-65 John F. Kennedy Memorial Bridge over the Ohio River at Louisville. Several nondestructive evaluation methods including acoustic emission monitoring, penetrant testing, ultrasonic testing and radiographic testing were used to evaluate a weld/crack repair on an H beam made from quenched and tempered steel. No defects were detected during the course of testing, indicating that the repair was properly affected. Technical aspects of the nondestructive evaluation work are presented along with test findings and recommendations fora structural reliability assessment of the bridge fracture critical members made from quenched and tempered steel.
