The video shows the automatic generation of wind loads using the load generator in RFEM. As an example, the wind load is determined for a three-dimensional steel hall according to Eurocode.

In Germany, DIN EN 1991-1-4 with the National Annex DIN EN 1991-1-4/NA regulates the wind loads. The standard applies to civil engineering works up to an altitude of 300 m.

If the wind load for buildings or structures is to be determined by the simultaneous assumption of aerodynamic pressure and suction coefficients on the windward and leeward sides of the building, the correlation of the wind pressure on zones D and E of the wall surfaces may be taken into account.

RFEM and RSTAB allow you easily to consider wind load effects on a three-dimensional building according to ASCE/SEI 7‑16. This article explains the complex theory of entering wind loads in the software. You can find the wind load under "Tools" → "Generate Loads" → "From Wind Loads".

In RFEM 5 as well as RSTAB 8 in RF-/FOUNDATION Pro, you can save the foundation dimensions for all five foundation types as foundation templates in a user-defined database and use them later in other models.
![Wind Load on Vertical Walls with Roof](/en/webimage/006843/1585331/001386-en-jpg.jpg?mw=512&hash=4258e32772a1d91dec18d9f426c84515295de896)
Wind loads can be automatically generated as member loads on the following structural components (optional with internal pressure for open buildings):
- Vertical walls
- Flat roofs
- Monopitch roofs
- Duopitch/troughed roofs
- Vertical walls with roof
The following standards are available:
-
EN 1991-1-3 (incl. National Annexes)
-
DIN 1055-4
-
CTE DB-SE-AE
-
ASCE/SEI 7-16

There are load generators available for beam structures, creating snow loads according to ASCE/SEI 7-10. The load cases are generated depending on the roof shape. Another generator creates coating loads (ice). You can save recurring load combinations as templates.

- Numerous component types, such as base and end plates, web angles, fin plates, gusset plates, stiffeners, tapers, or ribs for easy input of typical connection situations
- Universally applicable basic components (such as plates, welds, bolts, auxiliary planes) for modeling complex connection situations
- Graphical display of the connection geometry with dynamic updating during the input
- Wide range of cross-section shapes: I-sections, U-sections, angles, T-sections, hollow sections, built-up cross-sections and thin-walled sections
- Library in the Dlubal Center with a large number of program-side template connections, including user-defined templates
- Automatic adaptation of the connection geometry based on the relative arrangement of the components to each other – even in case of subsequent editing of the structural components

In the ultimate configuration of the steel joint design, you have the option to modify the limit plastic strain for welds.
