Basic wind speed in U. The basic wind speed is basic on statistical data collected from airport across U. The wind speeds correspond to 3-second gust speeds at 33 ft above ground for exposure C category. The wind speeds represent year return period. Exposure A is deleted. A distinction was made surface roughness categories and exposure categories.
Interpolation between exposure categories is permitted by rational analysis. Wind is to be evaluated in the worst case of the two degree sectors either side of the wind direction. This also allow the building to be designed in different exposure in different direction.
A building located at edge of city or sea shore may be designed for exposure category in one direction and other exposure in other direction. Important fac tor, I for wind load. Hurricane prone regions with. Building enclosure and openings and protection: Examples of partially enclosed buildings: One side of the building has door opening that larger than other 3 sides.
Buildings in standard, essential and substantial hazard categories located in wind-borne debris regions shall be protected with impact-resistant covering or glazings windows at 1 below 60 ft 2 at 30 ft from roof with aggregate surface within ft of the building.
ASCE 7-05 & 02 Wind load calculation:
Building 60 ft or lower and height does not exceed least horizontal dimension. Minimum design wind load: ASCE provides two methods for wind load calculation: The simplified procedure is for building with simple diaphragm, roof slope less than 10 degree, mean roof height less than 30 ft, regular shape rigid building, no expansion joints, flat terrain and not subjected to special wind 07-005.
The analytical procedure is for all buildings and non-building structures. Each procedure has two categories: An adjustment factor is provided for different exposure and height. The wind pressure is the wind pressure in the table multiplied by adjustment factor and important factor. Apply to all buildings and other structures. 077-05

Urban and suburban areas, wooded areas or other terrain with numerous closely spaced obstructions having the size of single-family dwellings or larger. Open terrain with scattered obstructions having heights generally less than 30 ft.
Flat, unobstructed areas and water surfaces outside hurricane-prone regions including smooth mud flats, salt flats, and unbroken ice. Surface roughness B in upwind direction for ft or 10 times the height of the buildings. For buildings with mean roof 007-05 30 ft or less, the upwind distance is reduced to ft. Surface roughness D in upwind direction for ft or 10 times the height of the buildings. Expose D shall extend inland from the shoreline for a distance of ft or 10 times the height of the building.
Method of wind calculation: Analytical procedure Apply to all buildings and other structures. Dead and live loads Wind load calculation Seismic load calculation Ice load calculation Snow load calculation.
