Linear and Nonlinear Structural Analysis
The model is calculated linearly according to the linear static analysis or nonlinearly according to the large deformation analysis. In order to determine internal forces, results can be superimposed in combinations.
All member types can be calculated according to the linear static, second-order or large deformation analysis. The selection option is available for load cases and load combinations. Further calculation parameters are individually adjustable for load cases, load and result combinations. Thus, high flexibility regarding the calculation method and detailed specifications is ensured.
Loads can be applied incrementally. The increment option is especially useful for calculations according to the large deformation analysis. For members, you can consider shear deformations and apply internal forces to a deformed or undeformed structural system. In addition, RFEM allows you to perform post‑critical analysis.
It is possible to calculate independent substructures. Deformation development is displayed in a diagram during the calculation. In this way, you can easily evaluate the convergence behavior.
Imperfections can be applied to members, member lists, and continuous members. The numbering of members is not important. The SUPER-RC add-on module enables combinations of load cases across different models i.e. files. Thus, different construction stages can be determined.

Depending on stiffness, mass, and damping, structures react differently to wind action.
- How can I model a timber-concrete composite floor?
- Is it possible to parameterize models and loads with RFEM and RSTAB?
My license does not work, what can I do?
- Why is there no support force displayed even though I have modeled the member foundation?
- RFEM calculates all load combinations automatically according to the second-order analysis. Is it possible to deactivate this?
- Is it possible to change the font size of dimensions?
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?
- I would like to calculate a multi-span beam. Is it possible to automatically apply imposed loads by span (for the design of the largest supporting moment and moment in the span)?
- How the shear deformation of a member can be taken into account?
