Quick and Easy Automatic Generation of Loads and Combinations
Generation of Snow Loads
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 (European Union)
-
SIA 261 (Switzerland)
-

-
NBC (Canada)
-
CTE DB-SE-AE (Spain)
-
GB 50009 (China)
-
IS 875 (India)
Generation of Wind Loads
Wind loads are also not a problem in your design. You can automatically generate wind loads as member loads or area loads (RFEM) on the following structural components:
- Vertical walls
- Flat roofs
- Monopitch roofs
- Duopitch/troughed roofs
- Vertical walls with duopitch roof
- Vertical walls with flat/monopitch roof

Generating Member/Line Loads from Area Loads
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.
Generating Member Loads from Free Line Loads
Also for pure member models, such as girder grillages, there is a useful feature for you. Here you can define free line loads (for example, from conveyor belts) and transfer them proportionally to members.

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. Furthermore, you can also generate action and load combinations as well as design situations 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
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).
Accidental Design Situation
Do your structures also have to withstand unusual conditions? Then select the "accidental" design situation. Here, accidental actions such as earthquake, explosion loads, collisions, and many others, are considered automatically. Furthermore, when using German standards, you can select the "Accidental - Snow" design situation to consider the "North German Plain" automatically as well.
Action Combinations
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.
Load Combinations
RFEM 6 offers you a wide range of helpful and efficient functions for working with load combinations. You can add together the load cases included in load combinations and then calculate them in consideration of the corresponding factors (partial safety and combination factors, coefficients regarding consequence classes, and so on). Generate the load combinations automatically in compliance with the combination expressions of the standard. You can perform the calculation according to the linear static analysis, second-order analysis, or large deformation analysis, as well as for post-critical analysis. Optionally, you can define whether the internal forces should be related to the deformed or non-deformed structure.
Result 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.
Modifying Stiffnesses / Considering Initial Deformations
Do not lose track of stiffnesses and initial deformations. In the individual load cases or combinations, you have 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. You can also consider initial deformations from other load cases or load combinations.
