To determine the correct load, it is necessary to specify the position of the drifted snow according to nodes of the roof surface.
This way, you can quickly create two load cases: "Snow with Drifted Snow" and "Snow Without Drifted Snow."
Considering Snow Drift
In RFEM and RSTAB, snow drift is considered according to 5.3.4(3) of DIN EN 1991‑1‑3 for saw-tooth roofs.

In addition to the geometry and shape of a flat roof, you can also take into account the formation of an eaves area when generating the loading.
The automatic creation of combinations in RFEM and RSTAB with the "EN 1990 + EN 1991‑3; Cranes" option allows you to design crane runway beams as well as support loads on the rest of the structure.
In RFEM and RSTAB, snow drift is considered according to 5.3.4(3) of DIN EN 1991‑1‑3 for saw-tooth roofs.
The Eurocode for DIN EN 1991‑1‑4:2010‑12 describes wind loads acting on structural systems.
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.
Use the "Independent mesh preferred" option in the FE mesh settings to create an independent FE mesh for the integrated objects. This allows you to generate a significantly more detailed and precise FE mesh for individual objects that are integrated into one another.
In the "Edit Section" dialog box, you can display the buckling shapes of the Finite Strip Method (FSM) as a 3D graphic.
In RFEM 6 and RSTAB 9, you have the option to enter "Visual Objects" as guide objects. You can import the file formats 3ds, stl, and obj.
These objects allow you to create a better reference to the dimensions.
The online service "Snow Load, Wind Speed, and Seismic Load Maps" displays the snow load zones 1*, 1a*, 2*, and 3* for Germany. Where are these snow load zones defined?
I noticed deviations from my sources in the online service "Snow Load, Wind Speed, and Seismic Load Maps". Where can I find information about the sources of your online service?
I noticed deviations from the map of DIN EN 1998‑1 or DIN 4149 in the online service "Geo-Zone Tool: Snow Load, Wind Speed, and Seismic Load Maps". Can you tell me which map is current and thus governing?
Are the models and presentations from Info Day 2020 freely available, and can you send them to me?
