After a successful calculation of the structure in RFEM/RSTAB, the user switches to the RF-/LTB add-on module. At least one design case is created where you can define the members and sets of members to be designed, as well as the load cases, load combinations, and result combinations required for this design.
Members and sets of members can be selected easily using the graphical tools familiar from RFEM/RSTAB. The materials and cross-sections used in RFEM/RSTAB are already preset for the design. However, they can be modified and added as required. Extensive libraries are available for defining materials and cross-sections.
