Psf Roof Load Shed Roof

Many factors influence how a system responds to loading.

Psf roof load shed roof.

For example appendix a indicates that one type of clay tile roof system has a live load value of 20 psf and a dead load value of 15 psf. Af pa s appendix a lists a variety of live and dead load combinations for floors ceilings and rafters. The water content of snow may range from 3 for very dry snow to 33 for a wet heavy snow to nearly 100 for ice. To figure out the load on your roof take the depth of snow in feet and multiply it by the weight of a cubic foot of snow.

Here each square foot of roof system delivers 50 pounds of live load and 15 pounds of dead load 65 psf total to the structural support system. As shown in the technical drawing below the reeds ferry standard roof has a load capacity rated at 110 pounds psf more than the highest code requirement. It is measured in pounds per square foot psf. In order for a structure to be sound and secure the foundation roof and walls must be strong and wind resistant.

Thus a roof designed to carry a snow load of 20 lbs. However if the attic is intended for storage the attic live load or some portion should also be considered for the design of. Factors that influence. 2attic loads may be included in the floor live load but a 10 psf attic load is typically used only to size ceiling joists adequately for access purposes.

If the snow weighs 10 pounds per cubic foot and there are 1 5 feet on the roof each square foot of the roof is getting 15 pounds of pressure. All loads are listed as pounds per square foot of horizontal projection footprint area. Per horizontal square foot is expected to support nearly 12 inches of wet heavy snow. When building a structure it is important to calculate wind load to ensure that the structure can withstand high winds especially if the building is located in an area known for inclement weather.

On a roof with a slope greater than 4 to 12 the live load limit is typically adjusted downward from 20 psf to 15 psf to allow for the relatively greater dead load on the steeper roof. Reeds ferry works with eagle metal of dallas tx to ensure the structural integrity of our roof truss.
