![]() LVL wood beams are used in both hidden and visible applications for floor and ridge beams, joists and rafters, and headers and lintels. The span is also limited to the mode of transportation from the mill to the job site. Increasing to a 7” by 24” 2.1E 3100 and the span can be 60 to 80 feet depending on all variables. However, to support typical loads, it is usually doubled or tripled for those distances.Ī 3-1/2” by 7-1/4” 2.1E 3100 LVL beam can span to 20 feet, while a 3-1/2 by 9-1/2” will do 26 feet and greater thicknesses 30 feet or more. Increasing the depth of the 1-3/4” wide beam to 14” or more and to span 30 feet or more. ![]() ![]() A 1-3/4” by 7-1/4” (2×8) 2.1E 2800 LVL beam can span to 16 feet with a load duration of 100%, while a 9-1/2” deep one can span 20 feet, and an 11-7/8” up to 26 feet. LVL beam span varies by dimensions, stress grade, and loads. Common lengths usually range in 4-foot increments from 4 to 48 feet, with special orders reaching 60 to 80 feet in length depending on mill capabilities. The depth or thickness of the beams ranges from 5-1/2” like a dimensional 2×6 to 24”, with other common dimensional lumber thicknesses included. Common widths are 1-3/4” or single, 3-1/2” or double, 5-1/4” or triple, and 7” for quadruple. The span of laminated beams depends upon their width, depth, and potential loads. Additionally, the use of waterproof adhesives makes the beams acceptable for both interior and exterior applications. They are engineered to support greater loads over longer distances than other wooden beams. As a result, they are more than twice as strong as regular lumber of similar size, more uniform in dimensions, straighter, and resistant to twisting, bowing, and shrinking. LVL beams are made of laminated veneer lumber similar to plywood, except the grain of all layers is oriented longitudinally to mimic solid wood. How Far Can an LVL Beam Span Without Support? What Is the Minimum Bearing Length for an LVL Beam?.What Size LVL Laminated Beam to Span 16 Feet?.How Far Can an LVL Beam Span Without Support?.(Almost 2x what I need)Īgree with my assumption (in bold above)? So a double-ply LVL 3 1/2" x 9 1/2" x 11 ft beam can support 353 x 2 = 706 PLF. Using the Uniform floor load (PLF) tables from LP corp, I see that a single Total weight of supported floor: 55 x 154 = 8470 lbs.Īssuming beam is carrying 50% of this load (and the exterior wall carrying the other 50%) 8470/2 = 4235 lbs.īeam is (nearly) 11ft long. Using standard load estimates from LVL span tables: 40 psf live, 15 psf dead = 55 lb/sqft. Proper blocking will be done in the cellar belowĪrea of floor above the beam: 14' x 11' = 154 sqft.Due to orientation of floor above, only the left area of the floor will be supported by the beam (see sketch no.Interior wall, not carrying the roof load.of the LVL beams) and he wouldn't exactly give me an answer but he did say the key is determining the PLF (pounds per lineal foot) that the beam will carry. I talked to tech support at LPcorp (a mfg. I have the opinions from a couple contractors but I want to verify the size of the beam needed. Removing a load bearing wall and replacing with an LVL beam.
