For relatively large or relatively small surfaces, it can happen that the automatically created result values do not fit the model: In case of large surfaces, there can be too much result values, in case of small surfaces, too few.Screenshots

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)
- The RF‑CONCRETE Columns add-on module cannot determine any sufficient reinforcement. However, the columns can be easily designed in a comparative calculation. Can you help us?
- I perform fire resistance design in RF‑/CONCRETE Columns. Which source does the design formula according to Section 5.8.8 refer to?
- Why do I get the message 28) in RF‑CONCRETE Members, saying that I have to make a "calculation without second order effect" with the internal forces according to the gemetrically linear analysis?
- I cannot find DIN 1045 in the add‑on module for concrete, but I need it for an existing building. What can I do?
- Is it possible to use your own materials in RSTAB or RFEM in the add-on module "Concrete Reinforced Concrete Design"?
- How can I create a curved or curved section?
- How are the signs to be interpreted for the release results of the line release and line hinges?
- Is it possible to manually specify a longitudinal reinforcement for the 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?
