Cross-Section
Glossary Term
When creating a cross-section, all properties are defined which are necessary for a structural analysis: surface, moment of intertia, section modulus (see Figure 01). A distinction is made between various cross‑section types, such as rectangular or composite cross-section.
One cross-section has to be assigned to each member in RFEM and RSTAB. Many cross-sections are already stored in the library and can be selected there (see Figure 02).

Defining Arbitrary Nodal Load Sequence with Only One Member Load
Arbitrary point load distributions often occur in the load definition of member structures.
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.
- Where do I find the setting to specify the entered structural component as a "wall" or "slab"?
- "During the calculation of material non-linearity, the material with a decreasing branch of the diagram can be calculated with one load increment only." Why do I get this error?
- How do I display some results of all load cases in the printout report, but other results of the selected load cases only?
- Are the models and presentations from Info Day 2019 freely available, and can you send them to me?
- Are the effective length coefficients in the add-on modules for the aluminum and steel design automatically determined from the model or do I have to make adjustments?
-
Which units are specified in the result display of the support reactions (kN or kN/m)? A note about this is missing in the graphic.
In the case that the support reactions are given in kN/m, for which distance does the value apply? - I design a cross-section created in the SHAPE‑THIN program by using the RF‑STEEL EC3 add-on module, but the program shows the error message "ER006 Invalid type of c/t-part for cross-section of type General." What can I do?
-
Is it possible to specify shrinkage effects as loads?
-
Is it possible to calculate American steel cross-sections?
- The four plates, identically loaded, show different negative moments at the point of support. Is this a mistake?
