ASCE uses three different basic wind speed maps for different categories of building occupancies. Analytical procedure Apply to all buildings and other structures.
These maps provide basic wind speeds that are directly applicable for determining pressures for strength design. Examples of partially enclosed buildings: Important fac tor, I for wind load. The wind speeds represent year return period.
Nevertheless, the editor does not warrant, and assume no liability for accuracy and completeness of its content. A distinction was made surface roughness categories and exposure categories.
Loads and appropriate load combinations load factorswhich were developed to be used together, are set forth in two design methods: ASCE 7 provides minimum load requirements for the design of buildings.
Surface roughness B in upwind direction for ft or 10 times the height of the buildings. To determine wind-uplift resistance loads for a roof system, you would multiple the ultimate wind loads by the ASD wind-load factor 1.
Minimum design wind load: A asec located at edge of city or sea shore may be designed for exposure category in one direction and other exposure in other direction. Exposure A is deleted.

Dead and live loads Wind load calculation Seismic load calculation Ice load calculation Snow load calculation. The wind speeds correspond to 3-second gust speeds at 33 ft above ground for exposure C category. Flat, unobstructed areas and water surfaces outside hurricane-prone regions including smooth mud flats, salt flats, and unbroken ice.
Urban and suburban areas, wooded areas or other terrain with numerous closely spaced obstructions having the size of single-family dwellings or larger. For each building risk category, an importance factor and wind-load factor are then applied to determine ultimate wind loads. The wind pressure is the wind pressure in the table multiplied by adjustment factor and important factor. ase
In doing so, applying a load reduction factor of 0. Each procedure has two categories: Building enclosure and openings and protection: Surface roughness D in upwind direction for ft or 10 times the height of the buildings.
ASCE 7-05 & 02 Wind load calculation:
ASCE uses four basic wind speed maps for different categories of building occupancies. The basic wind speed is basic on statistical data collected from airport across U.
Designers are given the option to use either ASD or strength design. Wind is to be evaluated in the worst case of the two degree sectors either side of the wind direction. ASCE uses a single basic wind speed map.
Apply to all buildings and other structures. Expose D shall extend inland from the shoreline for a distance of ft or 10 times the height of the building. These changes affect how you determine wind-uplift resistance.
Generally, roof systems are designed using Ssce.

Method of wind calculation: The editor made reasonable effort of editing. Open terrain with scattered obstructions having heights generally less than 30 ft. Hurricane prone regions with.
