Wind Load Calculation Excel Sheet Eurocode [verified]
This guide explains the purpose, methodology, and key features of an Excel spreadsheet designed to automate the complex process of calculating wind actions on structures according to Eurocode 1.
5. Example Calculation (Quick Reference inside Sheet)
Input:
- ( v_b,0 = 24 , m/s ) (Typical inland region)
- Terrain Category II
- Building height ( h = 10m ), width ( b = 20m ), depth ( d = 15m )
Output (from sheet):
- ( q_p(10m) \approx 1.05 , kN/m^2 )
- ( c_pe ) for windward wall (Zone D) = +0.8
- ( c_pe ) for leeward wall (Zone E) = -0.5
- Net pressure on windward wall = ( 0.84 , kN/m^2 )
Part 7: Download and Customize – Pro Tips
While you can build from scratch, there are also pre-made templates. However, building your own ensures compliance with specific National Annexes.
Recommended structure for your Excel workbook: wind load calculation excel sheet eurocode
[Cover] → [Input] → [Terrain Table] → [q_p calc] → [c_f tables] → [c_sc_d] → [Summary Forces] → [Cladding Pressures] → [Charts]
Protect formula cells to avoid accidental editing, but leave input cells unlocked.
Use conditional formatting to warn if height > 200m (Eurocode limit). This guide explains the purpose, methodology, and key
Add a comments column referencing the exact Eurocode clause (e.g., "EN 1991-1-4:2005, §7.2.1") for auditability.
