6 X 8 Douglas Fir Beam Span Chart
What is a 6 X 8 Douglas Fir Beam?
A 6 X 8 Douglas Fir Beam is a type of lumber that is commonly used for structural purposes. It is known for its strength and durability, making it an ideal choice for supporting heavy loads or spanning long distances. The beam is made from Douglas Fir, which is a type of coniferous tree that grows in the Pacific Northwest region of the United States.
What is a Span Chart?
A span chart is a tool that is used to determine the maximum allowable span for a particular type of beam. The chart takes into account the size of the beam, the type of wood it is made from, and the load it will be supporting. This information is used to determine the maximum distance between supports that the beam can span without failing.
6 X 8 Douglas Fir Beam Span Chart
According to the 6 X 8 Douglas Fir Beam Span Chart, a beam made from this type of lumber can span a maximum of 13 feet 8 inches when supporting a roof load only. If the beam is supporting a floor load as well, the maximum span is reduced to 11 feet 6 inches. It is important to note that these values are based on uniformly distributed loads and that other factors such as beam deflection and vibration may need to be taken into account when designing a structure.
Uses for 6 X 8 Douglas Fir Beams
6 X 8 Douglas Fir Beams are commonly used in a variety of construction projects, including:
- Roofing systems
- Floor systems
- Wall framing
- Bridge construction
- Deck construction
Advantages of Using 6 X 8 Douglas Fir Beams
There are several advantages to using 6 X 8 Douglas Fir Beams in construction projects, including:
