Explanation of ASCE and ASCE

This also allow the building to be designed in different exposure in different direction. Building enclosure and openings and protection: A distinction was made surface roughness categories and exposure categories.

ASCE uses a single basic wind speed map. Building 60 ft or lower and height does not exceed least horizontal dimension.

The editor made reasonable effort of editing. Analytical procedure Apply to all buildings and other structures. Examples of partially enclosed buildings: For this edition, the ASD wind-load factor is 1. The content of this website was obtained and edited from various resources. Wind is to be evaluated in the worst case of the two degree sectors either side of the wind direction. Expose D shall extend inland from the shoreline for a distance of ft or 10 times the height of the building.

Exposure A is deleted. 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. The basic wind speed is basic on statistical data collected from airport across U.

Urban and suburban areas, wooded areas or other terrain with numerous closely spaced obstructions having the size of single-family dwellings or larger. Important fac tor, I for wind load. Dead and live loads Wind load calculation Seismic load calculation Ice load calculation Snow load calculation.

One side of the building has door opening that larger than other 3 sides.

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.

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. For buildings with mean roof height 30 ft or less, the upwind distance is reduced to ft. Flat, unobstructed areas and water surfaces outside hurricane-prone regions including smooth mud flats, salt flats, and unbroken ice.

Each procedure has two categories: In doing so, applying a load reduction factor of 0. These maps provide basic wind speeds that are directly applicable for determining pressures for strength design.

ASCE 7 provides minimum load requirements for the design aece buildings. Comparing the edition to the edition, there was a significant change to the load factors used with wind and basic wind speed maps.

The wind pressure is the wind pressure in the table multiplied by adjustment factor and important factor. ASCE provides two methods for wind load calculation: Minimum design wind load: Method of wind ase An adjustment factor is provided for different exposure and height. Designers are given the option to use either ASD or strength design. Hurricane prone regions with.

Generally, roof systems are designed using ASD. For each building risk category, an importance factor and wind-load factor are then applied to determine ultimate wind loads. Open terrain with scattered obstructions having heights generally less than 30 ft. ASCE uses three different 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.

These changes affect how you determine wind-uplift resistance.

Apply to all buildings and other structures. Nevertheless, the editor does not warrant, and assume no liability for accuracy and completeness of its content.

ASCE 7-05 & 02 Wind load calculation:

Surface roughness D in upwind direction for ft or 10 times the height of the buildings. Surface roughness B in upwind direction for ft or 10 times the height of the buildings. Interpolation between exposure categories is permitted by rational analysis. ASCE uses four basic wind speed maps for different categories of asc occupancies.
