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

Loads and appropriate load combinations load factorswhich were developed to be used together, are set forth in two design methods: An adjustment factor is provided for different exposure and height. Method of wind calculation: For buildings with mean roof height 30 ft or less, the upwind distance is reduced to ft.

ASCE uses a single basic wind speed map. The wind pressure is the wind pressure in the table multiplied by adjustment factor and important factor. To determine wind-uplift resistance loads for a roof system, you would multiple the ultimate wind loads by the ASD wind-load factor 1.

ASCE 7-05 & 02 Wind load calculation:

Surface roughness D in upwind direction for ft or 10 times the height of ascf buildings. Expose D shall extend inland from the shoreline for a distance of ft or 10 times the height of the building. Comparing the edition to the edition, there was a significant change to the load factors used with wind and basic wind speed maps.


This also allow the building to be designed in different exposure in different direction. Interpolation between exposure categories is permitted by rational ascr.

Examples of partially enclosed buildings: Generally, roof systems are designed aece ASD. For this edition, the ASD wind-load factor is 1. ASCE 7 provides minimum load requirements for the design of buildings.

These changes affect how you determine wind-uplift resistance. 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.

Building 60 0705 or lower and height does not exceed least horizontal dimension. Minimum design wind load: Consequently, the strength design wind-load factor was changed to 1.

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. Urban and suburban areas, wooded areas or other terrain with numerous closely spaced obstructions having the size of single-family dwellings or larger.


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.

Explanation of ASCE and ASCE

A distinction was ascw surface roughness categories and exposure categories. 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. Dead and live loads Wind load calculation Seismic load calculation Ice load calculation Snow load calculation.

ASCE provides two methods for wind load calculation: Each procedure has two categories: Basic wind speed in U.

ASCE 7 & SEI Standards

ASCE uses four basic wind speed maps for different categories of building occupancies. Important fac tor, I for wind load.

The basic wind speed is basic on statistical data collected from airport across U. Nevertheless, the editor does not warrant, and assume no liability for accuracy and completeness of its content. The editor made reasonable effort of editing.
