This means that the span tables can change over time, so it’s important to stay up to date with the latest version of the Code. It’s also important to note that the span tables are based on the National Building Code of Canada, which is updated every five years. All of these factors should be taken into account when determining the maximum span for a beam. For example, a beam supporting a roof or floor is going to be under much more stress than one supporting a wall. Additionally, the size of the beam and its use also affect its ability to span. Different species of wood have different strengths, so the span tables are adjusted accordingly. The first is the species of lumber being used. When looking through the Lvl Beam Span Table, there are several important factors to consider. ![]() Understanding the Lvl Beam Span Table is a key part of any successful building project and will help to ensure the safety of everyone involved. One of the most important aspects of the Code is the Lvl Beam Span Table, which establishes the maximum length that a beam can span and still support the structure. The only time you would ever need to use bolts would be if the material had such severe deformities such as a bad “cup” which could not be overcome by nails.The Ontario Building Code is an essential part of staying safe when working on construction projects in the province. We have learned from our experience to use at least a 3 1/4″‘x.131″ groove shank nail in a column of four every foot apart down the laminate. staggered pattern with at least a 3″x.120″ nail. 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. On longer spans the beam may require much more bearing space as indicated by this table. 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. It has been my experience to never use a beam smaller than a two ply 2 x 8. This calculator matches up with 90% of the applications in the 2012 International Residential Code book. If there is are any questions about anything else, then you should contact your supplier or an engineer. Most interior beams need to include the roof load. You only have to select all of the loads that apply. This calculator takes all of this into consideration. 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. ![]()
