If your roof is pitched enter the length and width of the flat area covered by the roof.
Roof load width.
For the initial calculation f can be estimated at 1 000.
8000mm 2 4000mm.
This is the sixth video in the series on the timber framing code.
Length and width of your roof.
F stands for the beam s fiber strength in bending which depends on the species of wood.
You can enter these values in any units you d like including meters and feet.
Load limits on the roof of a building.
Step 2 determine dead load by identifying the amount of each construction material used in the roof.
You can enter this value either as a ratio x 12 or as an angle whichever suits you better.
So if the span was 8000mm and the roof pitch 20 degrees then.
Measure the length and width of the carport to determine the area of the roof in square feet.
The total load is 4 000 pounds.
L stands for the span of the beam in feet.
Multiply the length by the width to get the measurement for the area.
4000mm 20 cos 4256 71mm.
Intuitively this is the number of inches of snow on your roof in the place where the cover is the thickest.
Fill in the parts of the formula that are already known.
Roofs are under a lot of pressure.
In order to stay intact and in place a roof must be able to resist loads both permanent and temporary that are pushing.
If you can t measure along the top chord divide the span horizontally from plate to plate by 2 then with a scientific calculator divide by cos cosine and then the pitch of the roof.
