Knowledge of fatigue resistance of the material plays the key role during design and maintenance of the civil engineering structures. With this aim, the fatigue properties (Wohler field and crack propagation rate curve) of the S355 JO steel are analyzed according to both traditional and probabilistic models. In the latter case, the ProFatigue and ProPagation software programs are applied in the assessment of experimental fatigue data of S355 JO for derivation of the probabilistic S N field and fatigue crack growth rate curve, respectively, where data consist of results for different number of various investigated specimens subject to low cycle and high cycle fatigue with focus on the rolling direction. The results obtained are compared with the customary Basquin formula for the Wohler-curve and Paris law for the crack growth rate curve, both represented as straight lines in a double-logarithmic scale.
