Find the address or pick the regional centre — the calculator takes the characteristic snow and wind values of DBN V.1.2-2:2006 and adjusts them for altitude and terrain.
Snow, characteristic S₀1,670 Pa
Snow at your altitude1,670 Pa
Wind, characteristic W₀420 Pa
Wind at your altitude420 Pa
Wind at the building height W₀·Cₕ·Cₐₗₜ (DBN V.1.2-2, table 9.01)311 Pa
The region is the nearest regional centre (within 200 km). Above 500 m snow is multiplied by 1.4·H + 0.3 and wind by 2·H (H in km). The peak wind pressure qp is computed at the building height for terrain category II–IV (EN 1991-1-4).
The calculation is preliminary. A qualified engineer must check it before installation. Codes: DBN V.1.2-2:2006 (Ukraine) and the Eurocode; for other countries — snow and wind values from the national annex, entered by hand.
