Wind Load Calculation Excel Sheet Eurocode Verified May 2026
Finding a verified Excel sheet for wind load calculations according to Eurocode 1 (EN 1991-1-4) is essential for structural engineers who need automated, reliable results. Several platforms offer spreadsheets that automate complex factors like orography, terrain roughness, and pressure coefficients. Highly-Rated Eurocode Wind Load Spreadsheets
Table 3: Terrain & Exposure
- Input site data – Fundamental basic wind velocity (( v_b,0 )), terrain category, altitude, direction factor (( c_dir )), season factor (( c_season ))
- Compute basic wind velocity
[
v_b = c_dir \cdot c_season \cdot v_b,0
]
- Compute mean wind velocity at reference height ( z_e ):
[
v_m(z) = c_r(z) \cdot c_0(z) \cdot v_b
]
where ( c_r(z) ) = roughness factor, ( c_0(z) ) = orography factor (default 1.0).
- Compute turbulence intensity ( I_v(z) )
- Compute peak velocity pressure:
[
q_p(z) = [1 + 7 \cdot I_v(z)] \cdot \frac12 \rho \cdot v_m(z)^2
]
(with ( \rho = 1.25 , \textkg/m^3 ) as per EN 1991-1-4)
- Apply pressure coefficients ( c_pe,10 ) (for overall structural areas)
- Calculate wind force:
[
F_w = c_s c_d \cdot \sum (c_pe \cdot q_p(z_e) \cdot A_ref)
]
For structures with ( h \leq 15 , m ) and compact shape, ( c_s c_d = 1.0 ) (simplified).
