These maps provide basic wind speeds that are directly applicable for determining pressures for strength design.
Explanation of ASCE and ASCE
Open terrain with scattered obstructions having heights generally less than 30 ft. Method of wind calculation: This also allow the building to be designed in different exposure in different direction.
The basic wind speed is basic on statistical data collected from airport across U. Examples of partially enclosed buildings: The analytical procedure is for all buildings and non-building structures. Building enclosure and openings and protection: The editor made reasonable effort of editing.
Wind is to be evaluated in the worst case of the two degree sectors either side of the wind direction. ASCE provides 077-05 methods for wind load calculation: Loads and appropriate load combinations load factorswhich were developed to be used together, are set forth in two design methods: A distinction was made surface roughness categories and exposure categories.
ASCE 7 provides minimum load requirements for the design of buildings. Interpolation between exposure categories is permitted by rational analysis.
Analytical procedure Apply to all buildings and other structures. One side of the building has door opening that larger than other 3 sides. The wind pressure is the wind pressure in the table multiplied by adjustment factor and important factor. ASCE uses four basic wind speed maps for different categories of building occupancies. asxe
For buildings with mean roof height 30 ft or less, the upwind distance is reduced to ft. Minimum design wind load: Building 60 ft or lower and height does not exceed least horizontal dimension. 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. Expose D shall extend inland from the shoreline for a distance of 07-5 or 10 times the height of the building.
For this edition, the ASD wind-load factor is 1. Exposure A is deleted. Nevertheless, the editor does not warrant, and assume no liability for accuracy and completeness of its content.
Consequently, the strength design wind-load factor was changed to 1.

In doing so, applying a load reduction factor of 0. ASCE uses three different basic wind speed maps for different categories of building occupancies. The content of this website was obtained and edited from various resources.
The wind speeds represent year return period. ASCE uses a single basic wind speed map.
To determine wind-uplift resistance loads for a roof system, you would multiple the ultimate wind loads by the ASD wind-load factor 1. Apply to all buildings and other structures. Dead and live loads Wind load calculation Seismic load calculation Ice load calculation Snow load calculation.
Flat, unobstructed areas and water surfaces outside hurricane-prone regions including smooth asfe flats, salt flats, and unbroken ice. Important fac tor, I for wind load. Generally, roof systems are designed using ASD.

The wind speeds correspond to 3-second gust speeds at 33 ft above ground for exposure C category. For each building asxe category, an importance factor and wind-load factor are then applied to determine ultimate wind loads.
Surface roughness B in upwind direction for ft or 10 times the height of the buildings. These changes affect how you determine wind-uplift resistance.
