Fire Resistance Design for Reinforced Concrete Members
The reinforced concrete design for fire situations is carried out according to the simplified method based on EN 1992-1-2, Clause 4.2. The "zone method" described in Annex B.2 is used.

Concrete Design | Reinforced Concrete Design with Net Concrete Area
During the cross-section design, you can control whether the concrete surface is applied behind the reinforcing bars or is subtracted from the concrete cross-section. The design of the net concrete cross-section is mainly used for highly reinforced cross-sections.-
The limit stress is activated, but my stress ratio is “non-designable” in the Stress-Strain Analysis add-on. What could be the reason?
- In RFEM 6, is it possible to display a graphic with the distribution of the required reinforcement in the DIN A0 format?
- How do I define a member as a cantilever and not as supported at both ends for serviceability or deflection design?
- Where can I find the graphical results of punching shear in the concrete design? Especially the distribution of shear forces at the critical perimeter or the punching loads.
- Is it possible to display the reinforcement description in RFEM 6?
-
I would like to export nodal support forces of several load cases, load combinations and result combinations into an Excel spreadsheet in RFEM 6. How should I proceed?
- Where can find the option to hide the defined types (for example, design supports or effective lengths)?
- How do I create a user-defined Design Situation with my own chosen load combinations?
- Can I define a different bar size in the RFEM 6 Concrete Design add-on other than the default bar sizes available in the drop-down?
- Can the RFEM 6 Concrete Design add-on automatically design member and surface reinforcement?
- In RFEM 6, is it possible to display a graphic with the distribution of the required reinforcement in the DIN A0 format?
