The first window shows the maximum design ratios including the corresponding design of each designed load case, load combination, or result combination.
The other result windows list all detailed results sorted by specific subject in extendable tree menus. All intermediate results along the members can be displayed at any location. In this way, you can easily retrace how the module has performed the individual designs.
The complete module data are part of the RFEM/RSTAB printout report. You can select the report contents and extent specifically for the individual designs.

It is necessary to enter material, load, and combination data in RFEM/RSTAB in compliance with the design concept specified by Brazilian standard ABNT NBR 8800:2008. The RFEM/RSTAB material library already contains the relevant materials.
The RF-/STEEL NBR add-on module requires members and sets of members as well as load cases, load combinations, and result combinations to be designed.
- In the subsequent input windows, you can adjust preset definitions of lateral intermediate supports and effective lengths.
