Snow and wind loads

Snow and wind loads for a site in Poland follow PN-EN 1991-1-3 (snow) and PN-EN 1991-1-4 (wind) with the Polish National Annex (NA). Solispec computes loads by the Ukrainian DBN V.1.2-2 only, so this page shows no snow or wind values for Poland: 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.
