If the joists being supported span 12 feet and have no overhang, then you can use a double-ply beam spanning the equivalent of its depth in inches. A new build install is much like using standard lumber. So, a 2 x 8 beam is able to span 12 feet without support. Beams Ridge Beam Floor Beam Headers The WSDD is an extremely useful book (WSDD costs $20. The length of an LVL beam is governed by its width and depth. The beam calculator works off of a few questions. Changing member types automatically sets new defaults to the most common deflection limits, member spacing, and loading conditions. No matter what product you specify, structural performance is controlled by strength (Fb) and Stiffness (E). In order to estimate beam span, there is a simple method to follow. The Fb and E values are certainly no match for APB, LVL and PSL, but the performance of TimberStrand is impressive. Some manufacturers produce LVL up to 60 in length and some up to 80, but owing to shipping restrictions, most keep to 60. The beam may be a single width or made up of 3or 4 layers of 1-3/4 wide lengths. In this article, well identify what LVL beams are, their different sizes, how far they can span, and their different uses. Metal decking uses sheer studs, for instance. Once dried and trimmed, the sheets pass through a sander or grinder that flattens and smooths them to a consistent thickness. Conclusions:- The depth and width, as well as the length, contribute to the weight and may require a crane to lift it into place. The stacks then pass into a machine that produces high heat and pressure to ensure a strong, long-lasting adhesive bond between layers. We offer a range of exciting career opportunities for smart, talented people who are passionate about making a difference. The wood fiber used is strong and stiff. On longer spans the beam may require much more bearing space as indicated by this table. Works with evenly distributed loads only. In other words, some manufacturers do not base roof loads on horizontal projection, but rather base loads on the actual length of the rafter. a double 10 lvl is made by laminating of two 1 3/4 inches or 40mm thick and 9 1/2 deep LVL. There is always the factor of self-weight of the beam that will bear down on the columns. VERSA-LAM laminated veneer lumber (LVL) beams and headers eliminate twisting, shrinking and Although H3 and other chemically treated laminated boards may be used outside and exposed to a variety of weather conditions, the majority of LVL lumber is for dry indoor usage.

Calculate the size needed for a beam, girder, or header made from No. According to the 2012 IRC codesany beam, joist, or header shall never have a bearing of less than 1 1/2. Lumber Species. Its either going to an exterior or an interior load. To determine the depth of the beam you should use; heres a simple thumb rule using span of beam: the depth of the LVL beam should be equal to the span in inches divided by 20. The layers are heated, glued, and pressed together in different widths or thicknesses, and then cut to depths to meet various load requirements. As per general thumb rule and guidelines, a double 16 lvl beam can allow span upto 26 feet far distance used for residential building or projects. Beam depths are typically 5-1/2 inches, 7-1/4 inches, 9-1/4 inches, 11-1/4 inches, 11-7/8 inches, 14 inches, 16 inches, 18 inches and 20 inches. The thickness and depth of the required member will be listed. It has been my experience to never use a beam smaller than a two ply 2 x 8. The glued sheets are then stacked with the grain running longitudinally like solid lumber; not alternating longitudinally and latitudinally as with plywood. This calculator matches up with 90% of the applications in the 2012 International Residential Code book. The total span between members should not be greater than 60 feet. Since LVL design and strength depend on the manufacturer, which is proprietary to that company, and tributary load area and joist spacing affect the load, consulting a Structural Engineer is recommended. Select the proper span table for one or two floors, and determine the distance to span, the depth and breadth of the beam, the span carried by the beam, and the live or total load for a floor beam. We have learned from our experience to use at least a 3 1/4x.131 groove shank nail in a column of four every foot apart down the laminate. Select structural grades are special-ordered in many locations. Choosing the right size beam to span 20 feet can make all the difference. Cement (6) 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. Each manufacturer either provides span charts for their LVL products based upon different construction variables, so check the suppliers site for a span chart. The beam might be a single-width or 3-4 layers thickness of 1-3/4 wide lengths. It is typically used for headers, beams, rimboard, and edge-forming material. I have tried to simplify the process by choosing several popular materials and sizing them for a case-house. Works with evenly distributed loads only.
