Structural FEA Software RFEM 6 | Automatic Generation of Combinations

Structural Analysis & Engineering Software

Combinations of different elements do not have to degenerate into additional work. With RFEM, combinations are no longer a problem, but can be calculated quickly and easily. The FEA software RFEM allows for quick and easy modeling, structural and dynamic analysis, as well as design of models with member, plate, wall, folded plate, shell, and solid elements.

Due to the modular software concept, you can enhance RFEM with the various add-ons and thus apply it in a wide variety of areas.

Easy Modeling of Structures

“I really enjoy working with Dlubal Software programs. The structure generation and modification can proceed smoothly:

  • Manageability of functions in the menu and movability in space
  • Data transparency: checks, options to modify and transfer data

I am happy that I switched over to Dlubal Software!”

The Dlubal programs focus on efficient and uncomplicated work. Therefore, RFEM can automatically generate action and load combinations, as well as design situations according to Eurocode and other international standards. It follows the corresponding combination expressions. For example, you can also copy or add load cases in a clearly arranged window. Furthermore, the load cases and combinations can also be easily managed in tables.



With Dlubal, you can safely and easily design structures all over the world. Select from a large number of standards in the Base Data. You can also decide whether to create the combinations automatically.

Load Cases and Combinations

To ensure that your structures can cope with all loads, take a look at the "Load Cases and Combinations" dialog box. Here you can create and manage load cases. In addition, the action and load combinations as well as the design situations are generated here. You can assign the action categories of the selected standard to the individual load cases. If you have assigned several loads to an action category, they can act simultaneously or alternatively (for example either wind from the left or wind from the right).


Combination Expressions

You have come to the right place for the combination of actions. If you combine these in the ultimate limit states and serviceability limit states, you can choose between the different design situations according to the standard (for example ULS (STR/GEO) - permanent/temporary, SLS - quasi-permanent). Optionally, you can also include imperfections in the combination and select load cases that should not be combined with others (for example, roof assembly load not with snow load).


Accidental Design Situation

Do your structures also have to withstand unusual conditions? Then select the "Exceptional" design situation. Here, actions such as earthquakes, explosive forces, impacts and more are automatically taken into account. In addition, when applying the German standards, you can also automatically take into account the "North German Plain" by selecting the "Exceptional snow" design situation.


Action Combinations

Do you want to combine actions? Then use this feature. Here, the actions are superimposed according to the combination rules and shown as so-called "action combinations". You can define which combinations of actions will ultimately be considered for generating load or result combinations. The action combinations generated can also be used to estimate how the combination rules affect the number of combinations.


Load Combinations

RFEM 6 offers you a number of helpful and efficient functions for working with load combinations. You can add the load cases contained in the load combinations, taking into account the corresponding factors (partial safety values and combination values, factors relating to damage consequence classes, etc.) and then calculate them. Automatically generate the load combinations according to the combination rules according to the standard. The calculation can be carried out according to theory I., II., III. Order or strike through problem. For example, you can optionally select whether the internal forces should be related to the deformed or undeformed structure.


Result Combinations

Rely on RFEM 6 even for result combinations. First, you can have the contained load cases calculated in the result combinations. Then, the results are superimposed by taking into account the corresponding factors. In the result combinations, you can overlay the results of load cases, load combinations and other result combinations. The internal forces are added by default, but you have the option of a quadratic superposition, which is relevant for your dynamic investigations.


Modifying Stiffnesses / Considering Initial Deformations

Do not lose sight of stiffnesses and initial deformations. In the individual load cases or load combinations, you can modify the stiffnesses of materials, cross-sections, nodal supports, line supports, surface supports, member end hinges and line hinges either for all members or for selected members. You can also consider initial deformations from other load cases or load combinations.
