CONSIDERATION OF RUNOUTS BY THE EVALUATION OF F...

In EC3  the fatigue life of a steel structure subjected to a cyclic load is estimated by its
detail category. This category is based on the S-N  curves which are obtained by applying the
Basquin model. Statistically  this model does not allow extrapolating the S-N curves in the HCF
region  neither does it consider the runouts. This affects the fatigue life estimation when a
structure bears loading in HCF. To overcome these deficiencies  a new method based on a Weibull
distribution is applied.
