Snow and wind loads

Snow and wind loads for a site in Germany follow DIN EN 1991-1-3/NA (snow load zone, Schneelastzone) and DIN EN 1991-1-4/NA (wind zone, Windzone). Solispec computes loads by the Ukrainian DBN V.1.2-2 only, so this page shows no snow or wind values for Germany: enter the characteristic values from these documents in the designer’s «Own snow S0» and «Own wind W0» fields.

The frame calculation for such a site is preliminary: before installation it must be checked by an engineer who works to the country’s standards.
