This video looks at roof load width rlw.
Step 2 determine dead load by identifying the amount of each construction material used in the roof.
This is the sixth video in the series on the timber framing code.
Load limits on the roof of a building.
F stands for the beam s fiber strength in bending which depends on the species of wood.
L stands for the span of the beam in feet.
For the initial calculation f can be estimated at 1 000.
Measure the length and width of the carport to determine the area of the roof in square feet.
Rlw is used to calculate the sectional size of some roof members and supporting wall.
You can enter these values in any units you d like including meters and feet.
