Roof Snow Load Is Dead Load

Dead loads are the permanent loads which are always present.

Roof snow load is dead load.

15 psf x 14ft 210 pounds per lineal foot. The dead load on a roof is the weight of the roof structure itself along with any permanently attached materials or structures on the roof so it must be designed first of all to support itself. Dead loads depends upon the unit weight of the material. And also the permanent fixtures present in the structure.

910 pounds per lineal foot. In our case let s assume that our structure has a flat roof roof slope 5. The unit weight of commonly used building materials are given in the code is 875 part i 1987. If we compare total load live dead and total load snow dead the total load snow dead is 30 higher than total load.

It is important to list live load dead load and total load separately because live load is used to compute stiffness and total load is used to calculate strength. 65 or 46 of the total load snow dead is dead load. Flat roof snow loads p f the snow load that is applied to our structure is not the ground snow load but in most cases the flat roof snow load. Other considerations for sloped roofs can be found throughout chapter 7 of asce 7 10.
