Hurricane prone regions with. Generally, roof systems are designed using ASD. ASCE provides two methods for wind load calculation: Wind is to be evaluated in the worst case of the two degree sectors either side of the wind direction.

Nevertheless, ascs editor does not warrant, and assume no liability for accuracy and completeness of its content. Open terrain with scattered obstructions having heights generally less than 30 ft. Urban and suburban areas, wooded areas or other terrain with numerous closely spaced obstructions having the size of single-family dwellings or larger.

Surface roughness B in upwind direction for ft or 10 times the height of the buildings. 0-705 A is deleted. The content of this website was obtained and edited from various resources.

For each building risk category, an importance factor and wind-load factor are then applied to determine ultimate wind loads. Method ascr wind calculation: The simplified procedure is for building with simple diaphragm, roof slope less than 10 degree, mean roof height less ase 30 ft, regular shape rigid building, no expansion joints, flat terrain and not subjected to special wind condition.


Dead and live loads Wind load calculation Seismic load calculation Ice load calculation Snow load calculation. ASCE uses three different basic wind speed maps for different categories of building occupancies. Surface roughness D in upwind direction for ft or 10 times the height of the buildings. To determine wind-uplift resistance loads for a roof system, you would multiple the ultimate wind loads by the ASD wind-load factor 1.

Loads and appropriate load combinations load factorswhich were developed asxe be used together, are set forth in two design methods: This also allow the building to be designed in different exposure in different direction.

Minimum design wind load: Expose D shall extend inland from the shoreline for a distance of ft or 10 times the height of the building. Basic wind speed in U. Analytical procedure Apply to all buildings and other structures.

ASCE uses a single basic wind speed map. The wind speeds correspond to 3-second gust speeds at 33 ft above ground for exposure C category.

Important fac tor, I for wind load. Building 60 ft or lower and height does not exceed least 0-05 dimension. ASCE 7 provides minimum load requirements for the design of buildings.

Consequently, the strength design wind-load factor was changed to 1. Each procedure has two categories: An adjustment factor is provided for different exposure and height. Interpolation between exposure categories asve permitted by rational analysis. The wind pressure is the wind pressure in the table multiplied aece adjustment factor and important factor.


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. In doing so, applying a load reduction factor of 0. Designers are given the option to use either ASD or strength design.

Explanation of ASCE 7-05, ASCE 7-10, and ASCE 7-16

One side of the building has door opening that larger than other 3 sides. These maps provide basic wind speeds that are directly applicable for determining pressures for strength design.

Comparing the edition to the edition, there was a significant change to the load factors used with wind and basic wind speed maps. For buildings with mean roof height 30 ft or less, the 07–05 distance is reduced to ft. Examples of partially enclosed buildings: Flat, unobstructed areas and water surfaces outside hurricane-prone regions including smooth mud flats, salt flats, and unbroken ice.

ASCE uses four basic wind speed maps for different categories of building occupancies. Apply to all buildings and other structures.

The analytical procedure is for all buildings and non-building structures. The editor made reasonable effort of editing. The basic wind speed is basic on statistical data collected from airport across U. For this edition, the ASD wind-load factor is 1.
