Setting the Concrete Cover in RF-/FOUNDATION Pro According to EN 1992-1-1
Tips & Tricks
This article was translated by Google Translator
In RF-/FOUNDATION Pro, it is also possible to consider the concrete cover for the foundation according to EN 1992-1-1.
To do this, select the ‘Minimum cover acc. to Standard’ check box in Window 1.3 Materials. In the "Concrete cover according to standard EN 1992-1-1" dialog box, you can set all settings relevant for determining the minimum concrete cover (exposure classes, etc.). Depending on the selected settings, the minimum concrete cover of the reinforcement changes. You can see the value at the end of the dialog box.
The settings in the ‘Cbottom’ tab must always be specified. In the tabs ‘Ctop’ and ‘Cside/Cbucket’, the specifications can be imported from another tab or specifically adjusted. The parameters available in this dialog box for the determination of the concrete cover depend on the National Annex selected in Window 1.1 General Data. Thus, if you choose DIN EN 1992‑1‑1, for example the parameter ‘Design Working Life acc. to 4.4.1.2(5) Table 4.3N’ is not shown.
The concrete cover shown in Window 1.3 Materials window can also be adjusted subsequently. However, if the minimum concrete cover is activated, you can increase the concrete cover only manually.

Material Model Orthotropic Masonry 2D
The material model Orthotropic Masonry 2D is an elastoplastic model that additionally allows softening of the material, which can be different in the local x- and y-direction of a surface. The material model is suitable for (unreinforced) masonry walls with in-plane loads.
Frequently Asked Questions (FAQ)
- How can I create a curved or arched section?
- How are the signs for the release results of a line release and line hinges interpreted?
- Is it possible to manually specify a longitudinal reinforcement for design in RF‑PUNCH Pro?
- Can I simulate the cracked state of a concrete cross-section for a bending beam with the "Isotropic Nonlinear Elastic 1D" material model?
- Why is the deflection of the reinforced concrete floor sometimes greater when selecting a larger basic reinforcement?
- How can I view the depth of the concrete compression zone in RF‑/CONCRETE?
- I have a question about the message No. 47 in RFEM. What is the exact meaning of the word "integrate"? What is the resulting effect?
-
If I do not specify any basic reinforcement in RF‑CONCRETE Surfaces, I obtain the value X as an additionally required reinforcement. If I enter this value X as the provided basic reinforcement, I correctly do not get any additional required reinforcement.
However, if I enter a lower value than the determined required total reinforcement as the basic reinforcement, the additionally required reinforcement is increased in such a way that the originally required reinforcement content is exceeded. Why? - Why does the RF‑CONCRETE Surfaces add-on module not increase the amount of reinforcement until the SLS designs have a design ratio of 1.0?
- How can I get the member end forces to design the connections?
