Introduction to Windloading
Windloading
• Fd = Wind Loading Force
• Rho = Air density
• V = Wind speed
• A = Surface area
• Cd = Drage Coeffiecient

Description of the Windloading Ext.
What should the Capabilities of the extension be:
• a pressure should be calculated based on wind velocity;
• the pressure should be assigned in a direction;
• only positive pressures should be added;
• pressure should also be reduced based on the orientation of the element
and the loading direction;
• 2 loading type: constant or gradient loading across the height of the
construction;
• a shape factor can be assigned for different types of profiles (code check)
