![]() Remember always to consult manufacturer guidelines and, when in doubt, seek professional advice from a structural engineer to guarantee reliable results. By following these six steps, you will be able to accurately determine the right beam size for your specific application. ![]() ![]() They can help verify your calculations, ensuring that you select the correct LVL beam size for your project.Ĭalculating the appropriate LVL beam size for your project is crucial to ensure that your structure remains safe and stable. If you’re unsure about your beam size calculations or have a complex project with unique loading conditions, consider consulting a professional structural engineer. Step 6: Consult with a Structural Engineer (Optional) The table will provide a recommended beam size that can effectively support your project’s requirements without compromising safety or structural integrity. Using the span tables, locate the appropriate LVL size by cross-referencing your calculated total load and measured span length. Required end bearing length (based on 565 psi) is 3.0 unless the subscript + is shown. This is the total oor joist span to consider. If oor joists are not continuous above the beam, take the sum of the joist spans then multiply by 0.8. These tables are typically found on manufacturer websites or within product documentation. Table is based on continuous oor joist span and simple or continuous beam span con-ditions. Span tables are charts that provide information about allowable LVL sizes given various loading conditions and spans. Once you have all necessary data about loads and span length on hand, refer to manufacturer span tables or guidelines for their specific LVL products. Step 4: Refer to Manufacturer’s Span Tables The span length significantly affects beam sizing longer spans require larger beams capable of supporting increased loads without sagging. Measure the distance between supports where your LVL beam will be installed. Be sure to account for different loading conditions according to your specific project requirements. Next, calculate the total load that your LVL beam will need to support by adding up all dead loads, live loads, and point loads along its length. – Point Load: A concentrated load applied at a specific location on the beam (e.g., support columns or posts). – Live Load: Temporary or non-permanent loads applied to a structure, such as furniture, people, and snow. – Dead Load: The weight of the structural components and other non-moving materials (e.g., flooring, walls, roofing). In this article, we will walk you through the basic steps to calculate the appropriate LVL beam size for your project.īefore you can properly size an LVL beam, you must first identify and understand the various loadings that will be applied to it. Understanding the proper sizing ensures that the beam can support the weight loads it will be subjected to without compromising structural integrity. Let's assume you have an LVL beam with a width of 5 inches, a depth of 12 inches, and it needs to support a uniform load of 1,000 pounds per square foot.Calculating the size of a Laminated Veneer Lumber (LVL) beam is an essential skill for any builder, architect, or homeowner involved in designing or building a structure.
