Question
When opening an RFEM file, the entries in RF‑CONCRETE Surfaces are lost. Is it possible?Answer
Yes, it is possible, for example, if a file (calculated in version 5.23.01) is opened in an older version (such as 5.20.01).
The add-on modules for reinforced concrete structures have no backward compatibility. This means that the module entries must be deleted, depending on the version change.
For instance, this may be necessary if there is a function or a feature contained in the latest program version, which was not yet available in the older version. To avoid compatibility problems, the entries in the add-on modules are removed.
In the example, the file from version 5.23.01 is opened in version 5.20.01. In this case, the entries from RF‑CONCRETE Surfaces will be lost. If you open it in the version 5.17.01, for example, the entries from RF‑CONCRETE Members is also lost.

To avoid the problem, it is recommended to conclude a service contract and use the current version of RFEM.

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.

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.

- Why is the deflection of the reinforced concrete floor sometimes greater when selecting a larger basic reinforcement?
- I have a question about message no.47 in the RFEM program. 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 get the value X as additionally required reinforcement. If I enter this value X as the existing 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?
