It also informs you whether you should immediately remove some of the snow or you can wait a little bit longer.
Roof snow load support.
Determine the load per square foot that the roof must support.
Make sure to not wait for too long though.
P s c s p f.
The sloped roof snow load p s shall be obtained by multiplying the flat roof snow load p f by the roof slope factor c s.
Overall a plan should be established by greenhouse operators before winter weather arrives.
The term snow load refers to the downward force on a structure s roof by the weight of accumulated snow and ice.
The live load depends on the maximum snow load in your area.
The dead load is constant and is estimated as 10 pounds per square foot for wood framed construction.
The roof load is composed of a dead load and a live load.
Basing on the roof parameters you specified in the first section our snow load calculator displays the maximum allowable snow cover thickness and snow weight.
To provide additional support in double poly covered greenhouses two by fours can be placed under weight bearing bow and purlin connections however snow removal may still be required.
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.
If your roof is 1 000 square feet the total snow load is 15 000 pounds of snow.
Snow loads acting on a sloping surface shall be assumed to act on the horizontal projection of that surface.
