The directional and season factors … The basic wind speed is basic on statistical data collected from airport across U.S. by a single wind map giving basic maximum wind speed in m/s (peak gust speed averaged over a short time interval of about 3 seconds duration). The database covered up to 25 years of wind records obtained in 49 The basic wind velocity is given as v b = v b,0 ⋅c dir ⋅c season where the fundamental value of basic wind velocity v b,0 is defined in EN1991-1-4 §4.2(1)P and its value is provided in the National Annex. This 2010 chart has not been adopted yet by the State of Florida, so, for now the 2007 chart will rule. The design charts for basic wind speeds currently in use in Brazil [1] were created in 1977, based on wind speed records from 1950 to 1974. Wind Zone I equates to a 70-mph fastest-mile wind speed.

The information reflects the ASCE maps electronically to speed up critical design … The mean monthly wind speed over the year in Lagos, Nigeria (meters per second). The values of basic wind speed (that is, peak gust velocity averaged over an interval of 3 sec) have been specified for the six wind zones of India. Utilizing the new wind speed maps necessitates the introduction of the terms V ult and V asd to be associated with “ultimate” design wind speed and the “nominal” design wind speed respectively. 0.02 ( or 50-year return period ) of this paper is to provide the wind.
