Glulam Beam Span Table

March 7, 2018

The use of glulam beams has become increasingly popular in modern construction, and for good reason. The strength and versatility of these engineered wood beams make them an economical solution for a variety of projects. While the benefits of glulam beams are well known, understanding the specifics of beam span tables is key to taking full advantage of these products in a safe and cost effective manner. In this article, we’ll take a look at glulam beam span tables and discuss the factors that go into determining their capacities.

Glulam beams, also known as glued laminated timber, are an engineered wood product created by laminating multiple layers of lumber together with a waterproof adhesive. The resulting product is strong, flexible, and dimensionally stable, making it an ideal choice for both residential and commercial applications. From structural support for roofs and floors, to bridge components, glulam beams can be used in a wide variety of scenarios. But how do you determine the right size beam for the job? That’s where glulam beam span tables come in.

Glulam beam span tables are designed to provide guidance on the appropriate size beam for a given load and distance. To select the right beam size, you’ll need to consider several factors including the type of wood, the species of wood, the moisture content, and the grade of the lumber. In addition, you’ll need to consider the design of the beam, the number of plies, and the method of anchoring. Once all of these elements have been taken into consideration, you can use a span table to determine the appropriate beam size for your application.

Span tables can vary based on the information used to create them. For example, if you’re using a span table from a manufacturer, you should always double check the design values to ensure they are appropriate for your specific application. It’s also important to note that span tables are only intended to provide guidance and should not be used as a substitute for proper engineering analysis.

When selecting a beam size from a glulam beam span table, the most important factor is the maximum span of the beam. This is the distance between supports; any greater distance will require a larger beam to safely handle the load. The maximum span will depend on the type and species of lumber used as well as the design and method of anchoring. Most span tables will also include information on live load capacity, which is the amount of weight a beam can safely hold without permanent deformation.

Once you’ve selected a beam size from the glulam beam span table, you’ll need to consider the other factors that may affect its performance. These include things like the environment, the type of finish, and the type of fasteners used. For example, if you’re using a glulam beam in an outdoor environment, you’ll need to choose a beam with a higher grade of finish to protect it from moisture and ultraviolet light. Additionally, you may need to use special corrosion-resistant fasteners to ensure the beam stays securely in place.

In conclusion, glulam beam span tables are an invaluable tool when designing and building with glulam beams. By taking into account the various factors that go into determining the appropriate beam size, you can ensure that your project is safe and cost effective. With careful consideration and proper engineering analysis, you can leverage the strength and versatility of glulam beams in your next construction project.
