To determine wind-uplift resistance loads for a roof system, you would multiple the ultimate wind loads by the ASD wind-load factor 1. The editor made reasonable effort of editing. ASCE uses a single basic wind speed map. Acse roughness B in upwind direction for ft or 10 times the height of the buildings. Flat, unobstructed areas and water surfaces outside hurricane-prone regions including smooth mud flats, salt flats, and unbroken ice.

Interpolation between exposure categories is permitted by rational analysis. Surface roughness D in upwind direction for ft or 10 times the height of the buildings.

A building located at edge of city or sea shore may azce designed for exposure category in one direction and other exposure in other direction. Comparing the edition to the edition, there was a significant change to the load factors used with wind and basic 0705 speed maps.

The analytical procedure is for all buildings and non-building structures. Dead and live loads Wind load calculation Seismic load calculation Ice load calculation Snow load calculation.

Building enclosure and openings and protection: 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.


One side of the building has door opening that larger than other 3 sides. ASCE uses three different basic wind speed maps for different categories of building occupancies.

A distinction was made surface roughness categories and exposure categories. Important fac tor, I for wind load. ASCE 7 provides minimum load requirements for the design of buildings.

ASCE 7-05 & 02 Wind load calculation:

For each building risk category, an importance factor and wind-load factor are then applied to determine ultimate wind loads. Wind is to be evaluated in the aace case of the two degree sectors either side of the wind direction. Hurricane prone regions with. Urban and suburban areas, wooded areas or other terrain with numerous closely spaced obstructions having the size of single-family dwellings or larger.

Nevertheless, the editor does not warrant, and assume no liability for accuracy and completeness of its content. Basic wind speed in U. ASCE uses four basic wind speed maps for different categories of building occupancies.

Examples of partially enclosed buildings: Consequently, the strength design wind-load factor was changed to 1. These maps provide basic wind speeds that are directly applicable for determining pressures for strength design.

The wind pressure is the wind pressure in the table multiplied by adjustment factor and important factor. Analytical procedure Apply to all buildings and other structures.

Explanation of ASCE and ASCE

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. Building 60 ft or lower and height does not exceed least horizontal dimension. Loads and appropriate load combinations load factorswhich were developed to be used together, are set forth in two design methods: For this edition, the ASD wind-load factor is 1.


These changes affect how you determine wind-uplift resistance. For buildings with mean roof height 30 ft or less, the upwind distance is reduced to ft. The basic wind speed is basic 077-05 statistical data collected from airport across U.

ASCE Wind load calculation

Designers are given the option to use either ASD or strength design. Each procedure has two ascf Generally, roof systems are designed using ASD. The content of this website was obtained and edited from various resources. Minimum design wind load: ASCE provides two methods for wind load calculation: The wind speeds represent year return period. Open terrain with scattered obstructions having heights generally less than 30 ft.

This also allow the building to be designed in different exposure in different direction. Apply to all buildings and other structures. 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. An adjustment factor is provided for different exposure and height.

In doing so, applying a load reduction factor of 0.
