These tables offer recommendations based on load, species, size, and other factors. Access a Span Table: Manufacturers of LVL products typically provide span tables specific to their products. staggered pattern with at least a 3″x.120″ nail. Span Length: Measure the distance over which the LVL beam or joist will span (e.g., in feet). ![]() The 2012 IRC code calls for a minimum of a 32″ O.C. Fasteningīeams of more than one ply must be fastened together with either nails or bolts. Solid Futurebuild LVL products are manufactured in accordance with AS/NZ 4357, Structural. On longer spans the beam may require much more bearing space as indicated by this table. Residential Span Tables available - refer to brochures below Supported by technical support and software from Futurebuild LVL designIT ® software suite available computeIT ® software suite available for specific engineering design. Anything 5′ and above we always at least double cripple. BearingĪccording to the 2012 IRC codes any beam, joist, or header shall never have a bearing of less than 1 1/2″. These small areas are usually door opening on the interior and people are trained that these areas are the strongest place in a house to be in the case of an emergency.

This will amount to twice as much load on the exterior walls compared to a building with a center wall. For example, if building is 24′ x 24′ and has trusses, and the load on the roof will be for 30 lb snow load and a ceiling with no storage will total out like this. The load on an outside wall with clear span trusses is exactly half the load on each wall. In other words, it is either going to be on an outside wall, or somewhere on the inside. Its either going to an exterior or an interior load. ![]()
