Roof Load Width

You can enter this value either as a ratio x 12 or as an angle whichever suits you better.

Roof load width.

Length and width of your roof. Load limits on the roof of a building. Intuitively this is the number of inches of snow on your roof in the place where the cover is the thickest. Measure the length and width of the carport to determine the area of the roof in square feet.

8000mm 2 4000mm. This video looks at roof load width rlw. The total load is 4 000 pounds. So if the span was 8000mm and the roof pitch 20 degrees then.

Multiply the length by the width to get the measurement for the area. F stands for the beam s fiber strength in bending which depends on the species of wood. In the example the beam spans the 10 foot width of the roof. L stands for the span of the beam in feet.

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. For the initial calculation f can be estimated at 1 000. This is the sixth video in the series on the timber framing code. Step 2 determine dead load by identifying the amount of each construction material used in the roof.

Fill in the parts of the formula that are already known. Rlw is used to calculate the sectional size of some roof members and supporting wall. If your roof is pitched enter the length and width of the flat area covered by the roof. Roofs are under a lot of pressure.
