Wind Load Calculation Excel Sheet Eurocode Verified Official

| Parameter | Formula Logic | Excel Formula Example | | :--- | :--- | :--- | | | $0.19 \times (z_0 / 0.05)^0.07$ | =0.19*(B18/0.05)^0.07 | | $z_min$ | Look up based on Terrain Category | (Terrain II = 2m, III = 5m, IV = 8m) | | $c_r(z)$ | $k_r \times \ln(\max(h, z_min) / z_0)$ | =B26*LN(MAX(B10, B27)/B18) | | $v_m(z)$ | $c_r(z) \times c_0(z) \times v_b$ | =B28*B19*B23 |

| Feature | Benefit | |---------|---------| | | Easy to modify and review. | | Drop‑down terrain categories | Prevents manual entry errors. | | Graphical output of ( q_p(z) ) | Visual check of pressure profile. | | Support for multiple wind directions | θ = 0°, 90°, etc. | | Zone‑based ( c_pe ) tables | Automatically selects correct zone (A, B, C, D, E for walls; F, G, H, I for roofs). | | National Annex selection | e.g., Germany (DIN), UK (NA to BS EN), France (NF). | | Dynamic factor ( c_sc_d ) calculation | For buildings with ( h > 15 ) m or ( f_1 < 5 ) Hz. | | Error checks / warnings | Flags unrealistic heights or missing inputs. | wind load calculation excel sheet eurocode verified
