Recently, the increasing use of High Strength Steel (HSS) can be observed in the field of civil engineering structures. The advantage of these materials is a particularly favorable strength/weight ratio. The behavior of these materials compared to standard structural steel is slightly different, and it also concerns fatigue resistance and susceptibility to corrosion, which are areas that are far from fully explored. The contribution is focused on the analysis of the fatigue resistance of bridge made from HSS, the prediction of damage of structural elements susceptible to the formation of a fatigue crack from the edge, and how these aspects are reflected in the design of a system of regular inspections of the structure during its operation.
