Our close relationship with Stora Enso provides James Jones & Sons Ltd with the confidence to offer a full range of LVL grades and billet sizes. JJLVL-Beam is a natural choice for highly loaded beams, whereas JJSLVL-Rim is the most cost-effective solution for rim material in timber frame structures. The LVL that James Jones supplies to the market is available in two grades, JJLVL-Beam and JJLVL-Rim, and three standard thicknesses - 30, 45 and 75mm, with depths to match the full JJI-Joist range. VERSA-LAM ® cover veneer lumber (LVL) beams or headers eliminate twisting, shrinking and split, and deliver flatter, calmer floors both structures. As a material, LVL is exceptionally strong with excellent load bearing capacity, homogeneous quality and good workability. ENGINEERED WOOD PRODUCTS (EWP) LVL SPAN AND SIZE CHARTS.

Lvl beam span table code#

With the purlin/bracing installed, the long rafter span would be broken into two shorter spans, thus allowing the rafter to carry additional load.īefore you decide on lumber sizing and span, consult your local building code officials to determine design loads for your area.LVL is an advanced wood product suitable for a wide range of structural applications, available in beam depths which complement our JJI-Joist range. You can break up a long span of rafters by installing a purlin and bracing on the underside.

When calculating the span of joists or rafters, use the horizontal distance between vertical supports. The number 1 grade material is more expensive than the #2 grade, but if you can use fewer or smaller number 1 grade joists or rafters in your design, you may actually save money.ĭepending on the availability and cost of various size framing materials, it may be more economical to use larger joists or rafters in your design because you can typically use fewer of them. For example, you can span a #1 grade (no knots) southern yellow pine joist a greater distance than a #2 grade of the same species (with knots). The lengths and sizes of joists vary depending on the species and quality of the lumber used. To calculate maximum spans of additional species of lumber, use the Span Calculator or the Span Tables for Joists and Rafters on the American Wood Council website.Ĭonsiderations when using the Rafter and Joist Span Tables

Contact your local building code officials to determine the building code for your area. Calculators are for use in Canada applications only. Select the application below you are looking to calculate. Weigh all of the elements when designing wood structures. Use these simple calculators to size Trus Joist TimberStrand LSL and Parallam PSL beams and headers. Some areas have wind and seismic conditions. Lateral support of beam compression edge is required at intervals of 24 o/c or closer. Design a beam width based on the fact that the typical width of an LVL beam is 1-3/4 inches to 3-1/2 inches. Span is based on the more restrictive of simple continuous beam span. To figure out or estimate of LVL beam size and their depth. Table indicates the number of 13/4 wide LVL plies to be used for the given application. 3100Fb-2.0E 3 WEST FRASERLVL FACTORED RESISTANCES (STANDARD TERM) Design Property Depth 1. To calculate the size of the LVL beam simply divide the span in inches by 20 which gives the depth of the beam and the width of the LVL beam 1/3 or 1/4 of its depth. All 16 and greater beam depths are to be used in multiple member units only. For example, some localities get large amounts of snow, whereas others get none. Lateral support of beam is required at bearing locations. Before determining the maximum spans for joists and rafters, you must know the load requirements for your region. (3) 10M stirrups are required at a maximum d/2 spacing for spans greater than 1 200 mm, where d is the distance from the top of the lintel to the level of the bottom reinforcing bar in the lintel.
