Wind Load Calculation and Load Classes
Wind load calculation per EN 1991-1-4, terrain categories, building height effects and FS series capacities.
EN 1991-1-4 Wind Load
Wind pressure: qp(z) = 0.5 × ρ × v²(z) × ce(z). Basic wind speed varies by country and zone.
Terrain Categories & FS Capacities
Cat 0 (sea) to Cat IV (dense city). FS1500: 1.5 kPa. FS3000: 3.0 kPa. FS7000: 7.0 kPa.
Line Load EN 1991-1-1
Residential: 0.5 kN/m. Commercial: 1.0 kN/m. Public: 1.5 kN/m. Stadium: 3.0 kN/m.
