How to calculate wind loads

High velocity winds apply pressures that are very difficult to withstand, and it is very important to design structures properly in order to be safe. The wind velocity (wind speed – mph) applies pressure with the wind’s force. In design, it is the three (3) second gusts of wind that need to be withstood. It is the intensity of this pressure that is called the “wind load”.

There are many variable that need to be considered when calculating wind loads according to the American Society of Civil Engineers (ASCE) and the International Building Code (IBC) guidelines.

Note: The IBC references the ASCE 7 guidelines for wind load calcualations. There are some differences that can apply, but this will be provided by your state (if you live in the USA), or area within your country.
