For the combination of actions in the ultimate and the serviceability limit state, you can select various design situations according to the standard (for example, ULS (STR/GEO) - permanent/transient, SLS - quasi-permanent, and others).
Furthermore, there is the option to integrate imperfections in the combination and to determine load cases that should not be combined with other load cases (for example, construction load for roof not combined with snow load).

In RF-/FOUNDATION Pro, the user can freely select the proportion of the relieving soil pressure by means of the factor kred.
In RF‑/CONCRETE Columns, different methods are available for defining the minimum longitudinal reinforcement. The minimum reinforcement can be selected according to the design standard used and/or specified by the user.
You can assign comments to each element in RFEM and RSTAB (structure element, load element, and so on). This can help to improve the overview and documentation of structures, as the comments appear in the printout report and, for example, certain objects can be filtered and displayed using the "Select Special" function.
A PDF version of the printout report can be created in two ways. The most common way is to use a PDF printer that must be previously installed. The printer will be controlled like a real printer.
The loading 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 analyses.
The calculation can be performed for all member types according to the linear static, second-order, or large deformation analysis. This selection option is available for load cases and load combinations. Additional calculation parameters are individually adjustable for load cases, load combinations, and result combinations. This ensures a high degree of flexibility with regard to the calculation method and detailed specifications.
In the individual load cases or combinations, there is the option to modify the stiffnesses of materials; cross-sections; nodal, line and surface supports; and member and line hinges for all or selected members. Furthermore, it is possible to consider initial deformations from other load cases or load combinations.
The load cases included in the result combinations are calculated first. Then, the results are superimposed by taking into account the corresponding factors. In the result combinations, you can superimpose the results of load cases, load combinations, and other result combinations. Internal forces are added together by default. However, there is the option of a square addition, which is relevant for dynamic analysis.
I am trying to import a DXF file. The file can be imported into the model, but it does not have the correct scale. Where is the problem?
My model is unstable. What could be the reason?
How can I permanently save the parameters in the "Units and Decimal Places" dialog box?
Is it also possible to consider friction at nodal support in RFEM or RSTAB?
When creating a new member, the existing member is divided into two members, or when adding a node on a member, a new perpendicular member is created.
Is there any option to prevent the members from being divided automatically?
Is there any option to prevent the members from being divided automatically?
The tables (or the navigator) are not displayed despite activating the table window (or the navigator). How can I make them visible again?
