Moreover, the maximum span for a double 9 1/4″ LVL need to be 15 feet, while the maximum span for a double 9 1/2″ LVL need to be 17 feet. In general, the maximum span for a double 5 1/2″ LVL need to be 10 feet, while the the maximum span for a double 7 1/4″ LVL need to be 13 feet. In addition, a double ply 18″ LVL beam can allow to span maximum distance of 30 feet. Moreover, a double ply 14″ LVL beam can allow to span maximum distance of 23 feet, a double ply 16″ LVL beam can allow to span maximum distance of 23 feet. In general, a double ply 10″ LVL beam can allow to span maximum distance of 16 feet, while a double ply 12″ LVL beam can allow to span maximum distance of 10 feet. More than 60 Feet there is difficulty in transportation and handling. It can be customised according to your requirement. LVL length are generally available in 24, 28, 32, 36, 40 and 44 feet with special order upto 60 Feet. It is available in thickness from 19mm (3/4 inches) to 178mm (7 inches). Lvl sizes may vary according to manufacturer but lvl standard thickness of 1 3/4 inches (one ply), 3 1/2 inches (2 ply), 5 1/4″ (3 ply) and 7 inches (4ply). LVL offer several advantages over technical milled lumber, it is made in factory under control specification and it is more stronger straighter and more uniform in size. LVL has a “maximum allowable bending stress” of 2,800 or 3,000 psi. Because of the wood’s dimensional stability, inspection times are often reduced, too. Use an LVL beam to eliminate twisting and splitting for quiet floors. LVL is a straight, enough strong wood that fights warping and shrinking, providing great stability for your projects. LVL is product of recent innovation they are result of new technology and economic pressure to make use of new wood species and smaller trees that cannot be used to make solid Lumber. LVL 2900Fb-2.The American wood Council National design specification for wood, lvl is type of structural composite lumber comparable to glued laminated timber (glulam). (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.
