Wind Load Calculation Excel Sheet Eurocode [Pro]
Use to warn if height > 200m (Eurocode limit).
Simplify for engineering: Use the tabular values from EN 1991-1-4 Table 4.11. wind load calculation excel sheet eurocode
=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"))) Better: Use a linear interpolation table for ( c_f ) based on ( h/d ) ratio and wind incidence angle. For buildings with height < 15 m and non-slender, ( c_s c_d ) can be taken as 1.0. For dynamic sensitive structures: Use to warn if height > 200m (Eurocode limit)
Then, use =VLOOKUP(z, TerrainTable, column_index, TRUE) to get ( c_e(z) ). In the "Peak Pressure" tab: For buildings with height < 15 m and
q_p(z) = q_b * c_e(z) * c_o(z)*2 Where ( c_o(z) ) is the orography factor (usually 1.0 unless on a hill).
| Height z (m) | Terrain II ( c_e ) | Terrain III ( c_e ) | ... | |--------------|----------------------|------------------------|-----| | 5 | 1.7 | 1.3 | | 10 | 1.9 | 1.5 | | 20 | 2.1 | 1.7 |
Introduction For structural engineers, calculating wind loads is not just a preliminary step—it is a fundamental requirement for ensuring the safety, serviceability, and economy of a structure. In Europe, the governing standard is EN 1991-1-4: Eurocode 1: Actions on structures - Part 1-4: General actions - Wind actions .
