Questions? By using this service, some information may be shared with YouTube. The load exerted on a building as a result of blowing winds is a factor of the square of the wind speed. Building owners and some specifiers and designers don't realize that the ratings apply to uplift pressures in pounds per square foot (psf), not wind speeds. Wind Speed (mph) 170, 175. Wind speed, or wind velocity, is a fundamental atmospheric rate. Ultimate Design Wind Speed | UpCodes The correlation between dynamic wind speed and static equivalent pressure is formulaic in nature. The wind load formula employed by the wind load calculator is a simplified version that allows getting a first estimate of the value of a lateral wind load. mph. The idea of a concrete ship may contradict your initial reaction concrete doesnt float. Know that wind velocity varies at various distances from the ground. Close this window and log in. Wind speeds are generally measured in miles per hour (mph) and need to be converted to an fps in order to correctly calculator the pressure. As one can imagine, one of the goals when designinga building, house, or any structure is that it can withstanddifferent types of loads without experiencing anydamage. In ASCE 7, the factors that would substitute for the Cd in your equation can be numerous and depend greatly on structural type, location (geographically and on the structure), shape, proximity to other structures, duration of wind, statistical factors and other considerations.
