Flat, unobstructed areas and water surfaces outside hurricane-prone regions including smooth mud flats, salt flats, and unbroken ice. Designers are given the option to use either ASD or strength design. Buildings in standard, essential and substantial hazard categories 07-5 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.

Building 60 ft or lower and height does not exceed least horizontal dimension. Examples of partially enclosed buildings: Hurricane prone regions with.

Method of wind calculation: Open terrain with scattered obstructions having heights generally less than 30 ft. ASCE uses four basic wind speed maps for different categories of building occupancies. Wind is to be evaluated in the worst case of the two degree sectors either side of the wind direction. Basic wind speed in U. ASCE provides two methods for wind load calculation: In doing so, applying a load reduction factor 0-705 0.


Aace enclosure and openings and protection: This also allow the building to be designed in different exposure in different direction. Expose D shall extend inland from the shoreline for a distance of ft or 10 times the height of the building.

The wind pressure is the wind pressure in the table multiplied by adjustment factor and important factor.

Surface roughness D in upwind direction for ft or 10 times the height of the buildings. Minimum design wind load: Generally, roof systems ascs designed using ASD.

ASCE uses a single basic wind speed map. ASCE uses three different basic wind speed maps for different categories of building occupancies. Comparing the edition to the asc, there was a significant change to the load factors used with wind and basic wind speed maps. The editor made reasonable effort of editing.

ASCE 7-05 & 02 Wind load calculation:

For buildings with mean roof height 30 ft or less, the upwind distance is reduced to ft. A distinction was made surface roughness categories and exposure categories. Nevertheless, the editor does not warrant, and assume no liability for accuracy and completeness of its content.


Analytical procedure Apply to all buildings and other structures. These changes affect how you determine wind-uplift resistance.

Exposure A is deleted. A building 07-50 at edge of city or sea shore may be designed for exposure category in one direction and other exposure in other direction.

An adjustment factor is provided for different exposure and height. 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 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: ASCE 7 provides minimum load requirements for the design of buildings.
