After opening the add-on module, it is necessary to define designed members/sets of members, load cases, load or result combinations for the fatigue strength design.
The materials from RFEM/RSTAB are preset and can be adjusted in RF-/STEEL Fatigue Members. The material properties listed in the respective standard are included in the material library.
The design requires damage equivalent factors as well as detail categories on the designed stress points to be considered in the calculation.
