This is the sixth video in the series on the timber framing code.
Roof load width formula.
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.
This video looks at roof load width rlw.
Multiply the length by the width to get the measurement for the area.
50 psf x 14ft 700 pounds per lineal foot.
If the number of members is labeled m and the number of nodes is labeled n this can be written as m 3 2 n.
Snow load thickness density the result snow load or the pressure exerted by the snow has the units of kn m or lbs ft.
Roof load area rlw u p span left u p span right or with fan struts.
Measure the length and width of the carport to determine the area of the roof in square feet.
910 pounds per lineal foot.
Step 2 determine dead load by identifying the amount of each construction material used in the roof.
You can also find the load per square meter or square foot of roofing by opening the advanced mode.
Roof load width rlw rafter span if placed at midspan otherwise span1 span2.
Rlw is used to calculate the sectional size of some roof members and supporting wall.
The formula for truss loads states that the number of truss members plus three must equal the twice the number of nodes.
