To build or use an effective spreadsheet, you must understand the logical flow of the Eurocode. The wind action is generally defined as a pressure ($w$) acting on the surface.
Wind load, also known as wind pressure or wind force, is the force exerted on a structure by wind. It's a critical consideration in the design of buildings, bridges, and other structures, as it can cause damage, deformation, or even collapse if not properly accounted for. Wind loads can vary greatly depending on factors such as location, terrain, and building height.
Using an Excel sheet for wind load calculation offers several benefits:
Because basic wind speeds, air densities, and safety factors vary across European borders, the spreadsheet must allow overrides for National Annexes (e.g., UK-NA, French-NA, German-NA).
