Technically Yes, but you'll need to check with your building inspector because there are codes regarding structure that vary from place to place, and the inspector isn't going to pass something based on my say so.
The old rule of thumb was 1 inch for 1 foot, so a 12 foot span would require a 2 x 12.
A 4 x 8 isn't equal to a 2 X 16, or even 2 2 X 8's, but it should do if the load isn't too great.
I'm guessing you want to go with 8" stock because you've got some headroom issues. You'd be better off structurally with an LVL (Laminated Veneer Lumber) or OSB (Oriented strand Beam) or a truss, but these are kind of pricey.
If you get in trouble see if they'll let you go with them on 12" centers.
What else can I help you with?
What size single span beam is needed for a span of 36 feet for 2nd story floor support in my garage and I have heat tubes in the floor so I can't install a column?
You will have to have an engineer spec that beam for you. You will save yourself time and money by cutting the span with a column.
Will a 8x4 beam support a 16 foot floor span?
Whether an 8x4 beam can support a 16-foot floor span depends on the load it will carry and the type of material used. Typically, an 8x4 (which I assume refers to an 8-inch by 4-inch beam) may not adequately support a 16-foot span for standard residential loads without additional support, such as posts or a different beam size. It's crucial to consult local building codes and a structural engineer for precise calculations and recommendations based on the specific application.
What size beam will span 16 feet for 35psf roof load?
To determine the appropriate beam size for spanning 16 feet under a 35 psf roof load, you would typically consult a span table or structural engineering guidelines. Generally, a glulam beam or a steel I-beam may be needed, with sizes varying based on factors like the beam material and specific load conditions. For a rough estimate, a glulam beam of about 3x12 or a steel I-beam around 8x10 inches could be suitable, but a structural engineer should be consulted for precise calculations and local code compliance.
What is the maximum span of a 2x12?
The maximum span of a 2x12 lumber depends on several factors, including the wood species, load conditions, and whether it is used as a floor joist or beam. Generally, for standard residential applications with a uniform load, a 2x12 can span approximately 12 to 16 feet. However, it's crucial to consult local building codes and a structural engineer for specific requirements and safety considerations.
How far can a 2x12 span?
The maximum span for a 2x12 beam depends on various factors, including the type of wood, load conditions, and whether it's used for floor joists or beams. Generally, a 2x12 can span approximately 16 to 20 feet for residential floor joists, assuming a typical load of 40 pounds per square foot. For heavier loads or different wood types, it's crucial to consult local building codes or a structural engineer for precise calculations.
What size single span beam is needed for a span of 36 feet for 2nd story floor support in my garage and I have heat tubes in the floor so I can't install a column?
You will have to have an engineer spec that beam for you. You will save yourself time and money by cutting the span with a column.
How far can a double 2x10 beam span without support?
A double 2x10 beam can typically span up to 12 feet without additional support.
What size I-beam is required for a basement beam that needs to span 25 feet and will support 2x10 floor joists spanning 12 feet?
These calculations are not difficult, but you must know the load (including the floor weight) that will be carried. And the deflections that the appropriate building regulations allow.
What is the maximum span for a 2x6 beam?
The maximum span for a 2x6 beam is typically around 10-15 feet, depending on the load it needs to support and the building codes in place.
What is the span of a beam?
250 Feet
What is the recommended pergola beam span for optimal structural support and durability?
The recommended pergola beam span for optimal structural support and durability is typically between 12 to 16 feet, depending on the material and design of the pergola. It is important to consult with a structural engineer or contractor to determine the specific beam span needed for your project.
Will a 8x4 beam support a 16 foot floor span?
Whether an 8x4 beam can support a 16-foot floor span depends on the load it will carry and the type of material used. Typically, an 8x4 (which I assume refers to an 8-inch by 4-inch beam) may not adequately support a 16-foot span for standard residential loads without additional support, such as posts or a different beam size. It's crucial to consult local building codes and a structural engineer for precise calculations and recommendations based on the specific application.
What size of lumber level is needed to span a distance of 20 feet?
To span a distance of 20 feet, a lumber beam of at least 2x10 size is typically needed for adequate support.
What is the span of a beam bridge?
250 Feet
What is the recommended patio roof beam span according to the patio roof beam span table?
The recommended patio roof beam span according to the patio roof beam span table is typically around 10-12 feet.
What is the recommended pergola beam span according to the pergola beam span chart?
The recommended pergola beam span according to the pergola beam span chart is typically around 12-16 feet, depending on the specific design and materials used.
