Roof Load Width

Roofs are under a lot of pressure.

Roof load width.

You can enter these values in any units you d like including meters and feet. The total load is 4 000 pounds. Length and width of your roof. You can enter this value either as a ratio x 12 or as an angle whichever suits you better.

In the example the beam spans the 10 foot width of the roof. This video looks at roof load width rlw. For the initial calculation f can be estimated at 1 000. L stands for the span of the beam in feet.

Multiply the length by the width to get the measurement for the area. Step 2 determine dead load by identifying the amount of each construction material used in the roof. Load limits on the roof of a building. 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. F stands for the beam s fiber strength in bending which depends on the species of wood. 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. If your roof is pitched enter the length and width of the flat area covered by the roof.

So if the span was 8000mm and the roof pitch 20 degrees then. Rlw is used to calculate the sectional size of some roof members and supporting wall. 4000mm 20 cos 4256 71mm. 8000mm 2 4000mm.
