The paper describes a non-destructive testing (NDT) technique used on suspender ropes to detect either cross section loss or broken wires located on either the interior or exterior of a rope. The technology relies on the principles of magnetostriction to generate a guided acoustic pulse that travels up and down the rope. Where there is a defect in the rope resulting from corrosion or fatigue …
The evaluation of the cables on a recently inspected suspension bridge provided an opportunity to rigorously test 80 wires removed from the cable. Full length stress-strain for the samples were developed. These curves were found to very from each other by as much as 13%, and calculations made to determine the effect on the estimated cable strength of this variation. It was found that the simple…
