This is the sixth video in the series on the timber framing code.
Roof load width formula.
Rlw is used to calculate the sectional size of some roof members and supporting wall.
15 psf x 14ft 210 pounds per lineal foot.
Roof load width rlw rafter span if placed at midspan otherwise span1 span2.
You can also find the load per square meter or square foot of roofing by opening the advanced mode.
Both sides of the equation should be equal in order to end up with a stable and secure roof structure.
910 pounds per lineal foot.
If you want to calculate these values by hand use the following formulas.
It is important to list live load dead load and total load separately because live load is used to compute stiffness and total load is used to calculate strength.
Measure the length and width of the carport to determine the area of the roof in square feet.
Multiply the length by the width to get the measurement for the area.
50 psf x 14ft 700 pounds per lineal foot.
The formula for truss loads states that the number of truss members plus three must equal the twice the number of nodes.
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.
