Technical Meeting SAFETY, ACCEPTANCE AND DISCARD OF WIRE ROPES – Nantes 1991

The ropes of many suspension structures are exposed to oscillations which cause increased alternating bending stresses at their terminations. The aim of the tests carried out was to investigate how the alternating bending of a locked coil rope in the neighbourhood of the cast socket effects its fatigue strength. In the tests a single locked coil rope was used (diameter 31 mm, breaking strength 985 kN). The compound cast sockets were tested both with and without soft lined protective sleeves which were attached at different distances in front of them.
