Wind Load Calculation Excel Sheet Eurocode //top\\ -

To calculate wind load according to Eurocode 1 (EN 1991-1-4), your Excel sheet should be structured to determine the Peak Velocity Pressure ( ) and subsequent Wind Pressures ( ) acting on specific surfaces. 1. Basic Wind Velocity (

While specialized software (like RoboStruct or Staad Pro) handles these calculations automatically, many engineers prefer—and often require—a transparent, hand-calculation approach. This is where an Excel spreadsheet becomes an indispensable tool. wind load calculation excel sheet eurocode

Step 5: Roughness Factor ( c_r(z) )

For ( z_min \leq z \leq 200 , m ):

=IF(AND(h/d>=1, h/d<=5), 1.3 - 0.3*(h/d -1)/4, 
 IF(h/d<1, 1.3, 
 IF(h/d>5, 0.8, "error")))

Where ( \rho = 1.25 , kg/m^3 ) (air density). To calculate wind load according to Eurocode 1

• At z = 6 m, q_p ≈ 0.55 kN/m2 → wall Cp windward +0.8 → p ≈ 0.44 kN/m2
• Internal c_pi = +0.2 → p_net ≈ 0.44 - 0.11 = 0.33 kN/m2
• Force on wall area (12 m × 30 m) → F ≈ 0.33 × 12 × 30 = 118.8 kN
• Overturning moment (approx centroid 6 m) → M ≈ 118.8 × 6 = 713 kNm
