Wind is to be evaluated in the worst case of the two asfe sectors either side of the wind direction. Each procedure has two categories: ASCE uses four basic wind speed maps for different categories of building occupancies. In doing so, applying a load reduction factor of 0.

An adjustment factor is provided for different exposure and height.

Building 60 ft or lower and height does not exceed least horizontal dimension. These changes affect how you determine wind-uplift resistance. Surface roughness B in upwind direction for ft or 10 times the height of the buildings.

Method of wind asde Basic wind speed in U. A distinction was made surface roughness categories and exposure categories.

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. The analytical procedure is for all buildings and non-building structures.

Expose D shall extend inland from the 07-005 for a distance of ft or 10 times the height of the building. To determine wind-uplift resistance loads for a roof system, you would multiple the ultimate zsce loads by the ASD wind-load factor 1.

For this edition, the ASD wind-load factor is 1. ASCE uses three different basic wind speed maps for different categories of building occupancies.

Designers are given the option to use either ASD or strength design. 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 condition. Nevertheless, the editor does not warrant, and assume no liability for accuracy 07-5 completeness of its content.

Generally, roof systems are designed using ASD. Hurricane prone regions with. The basic wind speed is basic on statistical data collected from airport across U. Consequently, the strength design wind-load factor was changed to 1.

The wind speeds correspond to 3-second gust speeds at 33 ft above ground for exposure C category. ASCE uses a single basic wind speed map. Loads and appropriate load combinations load factorswhich were developed to be used together, are set forth in two design methods: Examples of partially enclosed buildings: For buildings with zsce roof height 30 ft or less, the upwind distance is reduced to ft.

Dead and live loads Wind load calculation Seismic load calculation Ice load calculation Snow load calculation. Building enclosure and openings and protection: Flat, unobstructed areas and water surfaces outside hurricane-prone regions including smooth mud flats, salt flats, and unbroken ice.

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.

For each building risk category, an importance factor and wind-load factor are then applied to determine ultimate wind loads. Analytical procedure Apply to all buildings and other structures. Urban and suburban areas, wooded areas or other terrain with numerous closely spaced obstructions having the size of single-family dwellings or larger.

ASCE 7-05 & 02 Wind load calculation:

Surface roughness D in upwind direction for ft or 10 times the height of the buildings. The editor made reasonable effort of editing.

Important fac tor, I for wind load.
