outlines the standard procedures for predicting wind actions on structures. The Eurocode approach relies on a combination of geographic data, terrain characteristics, and structural geometry.
The spreadsheet aggregates the internal and external pressures to give the final design wind pressure acting on the surfaces:
What are you designing for (e.g., standard rectangular, pitched roofs, canopy roofs)?
：Hills, escarpments, and cliffs can significantly accelerate wind flow. If the site is located on or near such a feature, a factor (c_o(z)) > 1.0 is applied. wind load calculation excel sheet eurocode verified
Use standard styling (e.g., light yellow for user inputs, grey for automated outputs) to make data entry intuitive.
