Roof Load Width

L stands for the span of the beam in feet.

Roof load width.

If your roof is pitched enter the length and width of the flat area covered by the roof. This is the sixth video in the series on the timber framing code. Measure the length and width of the carport to determine the area of the roof in square feet. In order to stay intact and in place a roof must be able to resist loads both permanent and temporary that are pushing.

Step 2 determine dead load by identifying the amount of each construction material used in the roof. Intuitively this is the number of inches of snow on your roof in the place where the cover is the thickest. You can enter these values in any units you d like including meters and feet. You can enter this value either as a ratio x 12 or as an angle whichever suits you better.

For the initial calculation f can be estimated at 1 000. 4000mm 20 cos 4256 71mm. Multiply the length by the width to get the measurement for the area. This video looks at roof load width rlw.

Fill in the parts of the formula that are already known. In the example the beam spans the 10 foot width of the roof. Length and width of your roof. F stands for the beam s fiber strength in bending which depends on the species of wood.

Roofs are under a lot of pressure. So if the span was 8000mm and the roof pitch 20 degrees then. 8000mm 2 4000mm. The total load is 4 000 pounds.
