Abstrakt: | Broken wires were found in the cables of a bridge after 15 years in service and it was decided to fatigue test a spare length of the cable. This paper presents the results of the fatigue test on a large diameter (0 101 mm) locked coil cable of the bridge. The initial variable amplitude fatigue load was determined by measurements on the bridge. A high constant amplitude fatigue load was necessary to get wire failures in the cable. The test shows that the cable is capable of resisting the design load although deterioration of the cable is clearly visible on the outside of the cable. Based upon the results it was recommended not to take any replacement actions. Monitoring the cables every five years was recommended. |
