This site uses the now discontinued free Google geo data API which no longer works. 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. Please start using the new site at https: To find the windspeed for a specific site, select 788 of the following methods: Windspeeds are site-specific for the location provided and are found by interpolation of map contours to the anai 1-mph.
ASCE 7 Windspeed
Users are cautioned to provide the most accurate location for the building site by specifying either the known street address, city and state or the latitude and longitude to at least five 5 decimal places. The material presented in the windspeed report should not be used or relied upon for any specific application without competent examination and verification of its accuracy, suitability and applicability by engineers or other licensed professionals. While the information presented on this website is believed to be correct, ATC and its sponsors and contributors assume no responsibility or liability for its accuracy.
Without providing too much detail, the design windspeeds are different because the basis for wind design was service-level, fastest mile windspeeds in ASCEservice-level, 3-second gust windspeeds in ASCE and strength-level, 3-second gust windspeeds in ASCE It is assumed that the users of this site have competency to understand how to calculate and apply design wind loads to structural models of buildings or other structures.
Users of the information from this website assume all liability arising from such use. Click the radio button asxe decimal and then the coordinates auto-populate in the decimal location.
An underestimation of windspeed could result is a design that does not meet the requirements for minimum wind design xnsi for the building under consideration. ATC does not intend that the use of amsi information replace the sound judgment of such competent professionals, having experience and knowledge in the field of practice, nor to substitute for the standard of care required of such professionals in interpreting and applying the results of the windspeed report provided by this website.
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.
This site will be taken offline soon. Windspeeds are also provided for serviceability purposes for,and year return periods when using ASCE Users are cautioned to be sure to use the correct windspeed associated with the edition of ASCE 7 being used in the design.
