• Abstract:
  This report describes the development of a technique for obtaining a reliable assessment of the condition of steel bridge pins already determined by ultrasound to contain imperfections. The details of a technique for performing high-definition ultrasonic scans of pins in the field are described. Results demonstrating this technique on specially fabricated calibration pins with actual cracks and actual bridge pins in the field are presented. A mathematical model for tracing the propagation of ultrasonic sound rays is also described. This model can be used as a tool to help interpret scanned images of imperfect pins. The researchers recommend that future research be carried out to develop further the instrumentation equipment and models needed for accurate field assessment of steel bridge pins.
