The purpose of the “Windspeed Web Site” is to provide users with a site specific windspeed using the GPS coordinate system. On this website, users can retrieve windspeeds from ASCE 7-10, ASCE 7-05 and ASCE 7-93. Windspeeds are also provided for serviceability purposes for 10, 25, 50 and 100-year return periods when using ASCE 7-10.
The reason this utility is needed is that the spatial resolution of the windspeed maps that are displayed in ASCE 7 are not sufficient to determine a site specific windspeed. There are no reference city or town locations on the ASCE 7 windspeed maps and while county boundaries are shown, the resolution is affected when the maps are expanded large enough to distinguish the boundaries and approximate the city locations.
Windspeeds are site-specific for the GPS coordinates provided and are found by interpolation to the nearest 1-mph.
