Designers are given the option to use either ASD or strength design. Nevertheless, the editor does not warrant, and assume no liability for accuracy and completeness of its content. Interpolation between exposure categories is permitted by rational analysis.

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.

Comparing the edition to the edition, there was a significant change to the load factors used with wind and basic wind speed maps. Building 60 ft or lower and height does not exceed least horizontal dimension.

For buildings with mean 07-50 height 30 ft or less, the upwind distance is reduced to ft. Loads and appropriate load combinations load factorswhich were developed to be used together, are set forth in two design methods: ASCE uses three different basic wind speed maps for different categories of building occupancies.

The simplified procedure is for building with ssce 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 condition.


These maps provide basic wind speeds that are directly applicable for determining pressures for strength design.

Basic wind speed in U. This also allow the building to be designed in different exposure in different direction. Hurricane prone regions with. Apply to all buildings and other structures. One side of the building has door opening that larger than other 3 sides.

Consequently, the strength design wind-load factor was changed to 1. The editor made reasonable effort of editing.

Analytical procedure Apply to all buildings and other structures. Method of wind calculation: Wind is to be evaluated in the worst case of the two 07–05 sectors either side of the wind direction.

ASCE provides two methods for wind load calculation: Asxe and live loads Wind load calculation Seismic load calculation Ice load calculation Snow load calculation. ASCE uses a single basic wind speed map.

Surface roughness D in upwind direction for ft or 10 times the height of the buildings. In doing so, applying a load reduction factor of 0. ASCE uses four basic wind speed maps for different categories of building occupancies.

To determine wind-uplift resistance loads for a roof system, you would multiple the ultimate wind loads by the ASD wind-load factor 1. Buildings in standard, essential aece 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.

Minimum design wind load: Open terrain with scattered obstructions having heights generally less than 30 ft. ASCE 7 provides minimum load requirements for the design of buildings. Building enclosure and openings and protection: Urban and suburban areas, wooded areas or other terrain with numerous closely spaced obstructions having the size of single-family dwellings or larger.


Expose D shall extend inland from the shoreline for a distance of ft or 10 times the height of the building. The content of this website was obtained and edited from various resources.

ASCE 7-05 & 02 Wind load calculation:

xsce For each building risk category, an importance factor and wind-load factor are then applied to determine ultimate wind loads. Examples of partially enclosed buildings: Exposure A is deleted. The wind speeds represent year return period.

The analytical procedure is for all buildings and non-building structures. For this edition, the ASD wind-load factor is 1.

Explanation of ASCE and ASCE

Important fac tor, I for wind load. The basic wind speed is basic on statistical data collected from airport across U. Each procedure has two categories: Generally, roof systems are designed using ASD.

The wind pressure is the wind pressure in the table multiplied by adjustment factor and important factor. Surface roughness B in upwind direction for ft or 10 times the height of the buildings. An adjustment factor is provided for different exposure and height. 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. These changes affect how you determine wind-uplift resistance. A distinction was made surface roughness categories and exposure categories.
