Wind does not exert uniform pressure across a building. It creates zones of high suction (negative pressure) at edges and corners, and positive pressure on windward faces. External Pressure Coefficients ( Cpecap C sub p e end-sub Building Dimensions: Total height ( ), length parallel
This is the user interface where engineers input project-specific data. Use data validation dropdown lists to prevent input errors.
The exposure factor ( c_e(z) ) depends on terrain category and height. Eurocode provides tables. In Excel, you can use VLOOKUP or an approximate formula:
