Roof load width.

So if the span was 8000mm and the roof pitch 20 degrees then. 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. F stands for the beam s fiber strength in bending which depends on the species of wood. Rlw is used to calculate the sectional size of some roof members and supporting wall.

Multiply the length by the width to get the measurement for the area. Fill in the parts of the formula that are already known. 4000mm 20 cos 4256 71mm. In the example the beam spans the 10 foot width of the roof.

In order to stay intact and in place a roof must be able to resist loads both permanent and temporary that are pushing. This is the sixth video in the series on the timber framing code.
