S‐N curve for full‐locked coil ropes: Background to the verification in prEN 1993‐1‐11:2020

Many steel rope systems are subjected to fluctuating tensile loads and therefore can fail due fatigue. There indications that the fatigue resistance of full-locked coil ropes is somewhat lower than other types rope. Fatigue test data on have been collected, but they terminate at different conditions. A semi-empirical model employed extrapolate results full failure The resulting S-N curve being adopted for revision European standard prEN 1993-1-11.
