Which shape function is used in RFEM?
Answer
- 1D beam element:
element with rotational degrees of freedom - 2D plate element:
Lynn–Dhillon; MITC3; MITC4 – used in case of nonlinear calculation - 2D wall element:
with stabilized zero energy modes - 2D shell element:
shell element = plate element + wall element - 3D solid element:
element with rotational degrees of freedom; element without rotational degrees of freedom (with or without extra shape functions) gas element contact element

Design of Hollow Section Node with Automatic Data Import or Manual Input
In the RF‑/HSS add‑on module, you can analyze the connections for nodes at which hollow sections join. RF‑/HSS performs the ultimate limit state designs according to EN 1993‑1‑8:2005.

You can download here a wide range of structural models (for example, RFEM, RSTAB, or RWIND files) that you can use for training purposes or for your projects.
Frequently Asked Questions (FAQ)
- I have installed Rhino 7. When trying to export the model to RFEM, the data are not transferred. What do I wrong?
- How can I find out in which version of RFEM/RSTAB was the model saved?
- I cannot activate an add-on module by using a Remote Desktop. Can you explain the error message to me?
- How do I display the load combination description according to an action category, such as "D, L, W," instead of "LC1, LC2, LC3"?
- I design timber components. The deformations of load combinations deviate from the manual calculation exactly by the factor of the material partial safety factor. Why?
- I often edit the reinforcement provided by the program. Adjusting the reinforcement by using coordinates takes much effort and time if having several beams in the model. Is there any way to speed up the reinforcement editing?
- How can I edit the list of parameters by using the COM interface?
- Which programs can I use to calculate and design power plants?
- Why do I get low supporting moments for a single-span beam? There is an eccentricity assigned to the single-span beam.
- Is it also possible to run the Dlubal Software programs on a Mac with an M1 chip?
