The purpose of the “Wind Speed Web Site” is to provide users with a site specific wind speed using the GPS coordinate system. On this website, users can retrieve wind speeds from ASCE 7-10, ASCE 7-05 and ASCE 7-93. Wind speeds are also provided for serviceability purposes for 10, 25, 50 and 100-year return periods.
The reason this utility is needed is that the spatial resolution of the wind speed maps that are displayed in ASCE 7 are not sufficient to determine a site specific wind speed. There are no reference city or town locations on the ASCE 7 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.
