Make sure to not wait for too long though.
Roof snow load support.
The dead load is constant and is estimated as 10 pounds per square foot for wood framed construction.
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.
It also informs you whether you should immediately remove some of the snow or you can wait a little bit longer.
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 roof load is composed of a dead load and a live load.
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.
P s c s p f.
Determine the load per square foot that the roof must support.
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.
If your roof is 1 000 square feet the total snow load is 15 000 pounds of snow.
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.
The live load depends on the maximum snow load in your area.
Snow loads acting on a sloping surface shall be assumed to act on the horizontal projection of that surface.
