Your Excel formulas must dynamically handle the continuous functions defined in EN 1991-1-4. Terrain Roughness (

Applies EN 1991-1-4 §7.4.1 – includes end-zone corrections, slenderness factor ψ_λ, and force coefficient c_f . wind load calculation excel sheet eurocode

Eurocode calculates wind load by transforming a regional baseline wind speed into a dynamic velocity pressure. This pressure is then multiplied by aerodynamic coefficients to determine the net forces acting on specific structural surfaces. The framework accounts for: Geographic location and regional wind climates. Terrain roughness and surrounding topography. Structural dimensions, height, and geometric shape. Structural resonance and dynamic behavior. Step-by-Step Wind Load Calculation Procedure

The roughness factor accounts for the variability of ground friction. It changes based on the terrain category and height above ground level (
