If you know only the wind speed and a couple of the other variables for determining the required wind load, the DASMA website has a wind load calculator that determines the approximate psf requirements. This should only be used as a guide.
In order to determine the exact PSF requirements the following variables are required: wind speed (in mph), exposure category, door area, mean roof height, roof slope, directionality factor, surrounding topography, zone, positive or negative pressure and internal building pressure.
If you need further assistance, our Architectural Design support team can help you in translating building codes or determining the appropriate wind load. Contact us to discuss your project.
