![]() ![]() Sawn-Lumber span tables are convenient tools. Technical experts have computed many combinations of these variables and present a variety of solutions in the form of span tables. You can do these calculations yourself or you can use span tables. Formulas that determine the allowable span and size of a beam rely on a host of variables like species, grade, size, deflection limit and type of load. Structural ability of sawn- and engineered-wood beams are predicted through mathematical calculation. No matter what material we specify, beams must provide adequate strength, stiffness, and shear resistance. We will compare the performance and cost of sawn-lumber, LVL, Timberstrand, Parallam and Anthony Power Beam in several different applications. We know how to measure the forces acting on a beam, now we’ll use this information to choose the appropriate structural material to resist the loads. In Part 1, “ Calculating Loads On Headers and Beams“, we learned how to trace load paths and translate roof, wall and floor loads into pounds per lineal foot of supporting beam. Once the loads acting on structural beams are calculated, the next step is to size and select the appropriate beam. Some information contained in it may be outdated. By understanding the table and taking all the required factors into account, contractors can ensure that their projects are safe, up to code, and completed to the highest standards.Please note: This older article by our former faculty member remains available on our site for archival purposes. Overall, the Lvl Beam Span Table is an essential part of the Ontario Building Code and a key factor in any successful building project. This helps to ensure that the project is completed safely and to the highest standards. ![]() Using the table, a contractor can determine the maximum span their beam can safely support. This table provides the maximum allowable span for each species of lumber, as well as the size and load of the beam. Once all of these factors have been taken into consideration, the Lvl Beam Span Table can be consulted. For example, if the project is located in an area prone to seismic activity, the tables may be adjusted accordingly. Additionally, the span tables can vary depending on the location of the project and the type of construction being done. 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 Ontario Building Code is an essential part of staying safe when working on construction projects in the province. ![]()
