RF-/STEEL Fatigue Members | Design

The fatigue strength design is based on the analysis using damage equivalent factors. The damage equivalent stress ranges ΔσE,2 and ΔτE,2 related to 2*106 stress cycles have to be compared to the limit values of the fatigue strength ΔσC or ΔτC for 2*106 stress cycles of the corresponding detail, taking into account the partial safety factors.

In this way, the individual design requirements are specified. Separate design cases enable flexible analysis of selected members, sets of members, and actions, as well as of individual cross‑sections. Design-relevant parameters such as B. selecting the design concept as well as partial safety factors can be defined freely.
