Saving and Importing Diagrams for Member End Releases
In RFEM 5 and RSTAB 8, it is possible to assign nonlinearities to member end releases. In addition to the nonlinearities “Fixed if” and “Partial activity”, you can also select “Diagram”. If you select the “Diagram” option, you have to specify the according settings for the activity of the member end release. For the individual definition points, it is necessary to specify the abscissa and ordinate values (deformations or rotations and the according internal forces) that define the release.
Depending on the number of defined points of a diagram for the member end release, the necessary input can be quite extensive. To reduce the time for specification, you can save the specified diagram. If you want to insert a new member end release (also with the “Diagram” nonlinearity) at other member ends, you can import this saved diagram.
This functionality works across models, thus allowing you to import the defined diagrams in other RFEM and RSTAB models.

You can make various settings in order to achieve a clearly‑arranged display of the result values. For example, some users may not want the white background in text bubbles. You can adjust the background in ‘Display Properties’ using the option Transparent and Background color.
SHAPE-THIN determines the effective cross-sections according to EN 1993-1-3 and EN 1993-1-5 for cold-formed sections. You can optionally check the geometric conditions for the applicability of the standard specified in EN 1993‑1‑3, Section 5.2.
The effects of local plate buckling are considered according to the method of reduced widths and the possible buckling of stiffeners (instability) is considered for stiffened sections according to EN 1993-1-3, Section 5.5.
As an option, you can perform an iterative calculation to optimize the effective cross-section.
You can display the effective cross-sections graphically.

Is it possible to calculate American steel cross-sections?
- Where do I find the setting to specify the entered structural component as a "wall" or "slab"?
- How can I quickly model a chimney with reinforcement rings and stiffeners?
- How can I model and design general bolted connections with the surface and solid elements in RFEM?
- I get the message "Existing torsion -> no stability design possible." Why does this appear and what can I do?
- I design an asymmetric cross-section and get the message: "Non-designable: ER051) Moment about z‑axis on asymmetric cross-section, taper or set of members." Why?
- How can I consider holes in steel members?
Is it possible to model and design tapered castellated beams in RF-STEEL AISC?
- I would like to convert the load from a surface load to a line load, that is, to apply it to the individual beams. How can I do this without using an auxiliary area?
Why are my steel members not being designed for stability in RF-STEEL AISC?
