After entering the model in RFEM/RSTAB, it is possible to open the RF-/FE-LTB add-on module. Here you can define continuous members and load cases or combinations to be designed in a design case.
The continuous members can be selected graphically as well. The materials and cross-sections used in RFEM/RSTAB are already preset but can always be adjusted, if necessary. Extensive libraries are available for this purpose.
