I can review your wind-load Excel sheet for Eurocode compliance. Please either paste the key parts (formulas, assumptions, inputs, and any screenshots) here or upload the file. I’ll check: scope & standards used, input units, formulas for q, z, z0, cdir, cseason, cscd, Ct, Cpe/Cpi, gust factors, exposure/terrain categories, reference heights, combination factors, and result sanity (units and magnitudes), then list errors, omissions, and fixes with corrected formulas and a short test case.

Excel:
q_b = 0.5 * rho * v_b^2

Step 3: Terrain Category & Roughness Length ( z_0 )

Eurocode defines 5 terrain categories (0 to IV): wind load calculation excel sheet eurocode
