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 consider a sway bracing in CRANEWAY?
Can a model be adjusted retroactively after it has been created with the model generator?
- I have defined a tapered member consisting of two different cross -sections in RSTAB/RFEM. This is now displayed incorrectly in the rendering (see the "Incorrect taper" graphic). What did I do wrong?
- Where do I find the setting to specify the entered structural component as a "wall" or "slab"?
- The protocol lacks information on the limit time for the assessment of fire resistance R in the RF-TIMBER Pro add-on module. Can this information be added to the report?
Where can I set the units of the results in RFEM/RSTAB?
I would like to display global deformation with values, ideally colored according to the size. Is it possible to set this?
- I would like to export nodal support forces of several load cases, load combinations and result combinations into an Excel spreadsheet. How should I proceed?
- Where can I find the internal forces at certain nodes in the printout report?
- How can I model a timber-concrete composite floor?
