Answer:
The basis for calculating a snow load is a snow load zone where the structure is located. The best way to determine the snow load zone as well as the characteristic value of the snow load is to use our online service, Geo-Zone Tool for Load Determination. You can find it on the Dlubal Software website:
Snow Load, Wind Speed, and Seismic Load Maps
In addition to the snow load zone, this tool can determine a wind zone as well as an earthquake zone for any location. In addition to the load maps of Germany, the Dlubal Software web application provides many other countries and standards to select.
