Wind Load Calculation Excel Sheet Eurocode Verified Instant

This advanced Excel spreadsheet is designed to automate the calculation of wind actions on structures following the guidelines set out in Eurocode 1: Actions on Structures (EN 1991-1-4). It serves as a vital tool for structural engineers, architects, and civil engineering students, ensuring that wind load derivations are accurate, reproducible, and compliant with current European standards.

The sheet eliminates the need for manual interpolation of complex tables and reduces the risk of human error in calculating peak velocity pressure and force coefficients.

Worksheet “Input & Site” sample row:

| Parameter | Value | Unit | Eurocode Clause | |-----------|-------|------|------------------| | Fundamental basic wind velocity ( v_b,0 ) | 26.0 | m/s | NA.2.1 | | Terrain category | II | – | 4.3.2 | | Building height ( h ) | 12.0 | m | – | | Building width ( b ) | 15.0 | m | – | | Building depth ( d ) | 20.0 | m | – | | Orography factor ( c_0 ) | 1.0 | – | 4.3.3 | | Air density ( \rho ) | 1.25 | kg/m³ | 4.5(1) | wind load calculation excel sheet eurocode verified

Output area – Peak velocity pressure ( q_p(z_e) ): 0.94 kN/m²

The Excel file consists of four main worksheets:

| Worksheet Name | Function | |----------------|-----------| | Input & Site | User inputs location, terrain category, building dimensions, basic wind velocity (or NUTS region) | | Wind Velocity | Calculates ( v_b, v_m(z), q_p(z) ) with automatic terrain roughness table | | Pressures & Forces | Computes external pressures on walls and roof zones (F, G, H, I for flat roof) | | Verification | Benchmark results vs. EN 1991-1-4 example (Appendix A of the code) |

Key Excel features used:

The spreadsheet was cross-checked against WindLoad Calculator v2.3 (commercial software verified to Eurocode). For a test case (Terrain II, ( v_b,0=30, m/s, h=15,m )):

| Output | Excel | WindLoad v2.3 | Difference | |--------|-------|---------------|-------------| | ( q_p(15) ) (kN/m²) | 1.172 | 1.169 | +0.26% | | Total force (kN) | 87.4 | 87.2 | +0.23% |

Difference < 0.3% – considered acceptable for engineering practice. This advanced Excel spreadsheet is designed to automate
