Create a lookup table in sheet "Terrain":
Simplify for engineering: Use the tabular values from EN 1991-1-4 Table 4.11.

[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.
Then, use =VLOOKUP(z, TerrainTable, column_index, TRUE) to get ( c_e(z) ). In the "Peak Pressure" tab: Create a lookup table in sheet "Terrain": Simplify
This article provides a complete guide to building a . We will cover the theoretical background, step-by-step formulas, Excel implementation tips, and a practical example. Part 1: Understanding the Eurocode 1 Wind Load Framework Before opening Excel, we must understand the key equation. According to EN 1991-1-4, the peak velocity pressure ( q_p(z) ) and the resulting wind force on a structure are calculated as follows: 1.1 The Basic Wind Force Equation For a structure or element, the wind force ( F_w ) is:
While commercial software exists, many engineers prefer the transparency, customizability, and cost-effectiveness of a well-structured . An Excel-based wind load calculator allows you to understand every variable, apply national annexes, and avoid "black box" engineering. In the "Peak Pressure" tab: This article provides
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).
