•Fatigue Limit State (FLS)
Important limit state ensuring a proper margin against fatigue failures.
Limit state formulation:
Fatigue Life Calculated > nf * Structural Design Life
nf = 1, 2, 3 or 10 depending on severity of a fatigue failure.
10 is used for cases with large consequences which additionally is difficult to inspect.
NB! If a safety factor of 10 is found for a detail where inspection canbe made, one can not skip inspections.
