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

In Germany, DIN EN 1991-1-3 with National Annex DIN EN 1991-1-3/NA regulates snow loads. The standard applies to civil engineering works at altitudes of up to 1,500 m above sea level.
Eurocode 1, Parts 1 to 3, and American standard ASCE/SEI 7-16 describe the general effects due to snow loads. The load applications for duopitch, monopitch, and flat roofs required by the standards are stored in a tool in RFEM and RSTAB so that these effects can be generated easily.
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.
In RF-/FOUNDATION Pro, the foundation design requires the definition of the corresponding loading (load cases, load combinations, or result combinations) for different design situations (STR, GEO, UPL, or EQU).
Snow loads can be generated as member loads on flat/monopitch roofs and duopitch roofs.
Additional snow loads such as drifted snow loads, snow overhangs, and snow guards can be taken into account as well.
The following standards are available:
- EN 1991-1-3 (incl. National Annexes)
- DIN 1055-5
- 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.
In the "Edit Section" dialog box, you can display the buckling shapes of the Finite Strip Method (FSM) as a 3D graphic.
