3D FEA Software RFEM 6 | Automatic Generation of Loads and Combinations

Do your structures also have to withstand snowfall? Use the Snow Load Wizard to generate snow loads as member loads or surface loads.

The following standards are available:

• EN 1991-1-3 (incl. National Annexes)
• ASCE 7
• NBC
• SIA 261
• CTE DB-SE-AE
• GB 50009
• IS 875

Use all types of loads without any difficulty. You can automatically convert the area loads into member loads or line loads (RFEM).
In the case of member loads from area loads, you have to define a plane via corner nodes or select cells in the graphic. Then the rest works by itself.

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.

For the combination of actions, you have come to the right place. If you use them 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). Optionally, you can also integrate imperfections in the combination and determine load cases that should not be combined with other load cases (for example, construction load for roof not combined with snow load).

Do you want to combine actions? Then use this feature. Here, the actions are automatically superimposed in accordance with combination expressions and then displayed as "action combinations". You can define which action combinations will eventually be used for the generation of load or result combinations. Based on the created action combinations, you can estimate how the combination expressions affect the number of combinations.

Rely on RFEM 6 even in the case of 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 superimpose the results of load cases, load combinations, and other result combinations. Internal forces are added together by default. However, you have the option of a square addition, which is relevant for dynamic analysis.
