As a structural engineer, I've worked on numerous projects that require the use of 2x8 LVL spans. These are laminated veneer lumber beams that have the strength and stability to support heavy loads over long spans. In this article, I will be sharing 10 things you need to know about 2x8 LVL span.
1. What is 2x8 LVL span?
2x8 LVL span is a type of engineered wood product. It is made by layering thin sheets of wood together using a special adhesive. This process results in a strong, stable beam that can support heavy loads over long distances. 2x8 LVL span is commonly used in construction for floor and roof framing, as well as in other applications where the span needs to be longer than a traditional 2x8 framing member.
2. The advantages of using 2x8 LVL span.
There are several advantages to using 2x8 LVL span. First, it is stronger than traditional framing lumber, which means it can support heavier loads while spanning longer distances. Second, it is less prone to warping and twisting than traditional framing lumber, which makes it easier to work with and results in a more stable structure. Finally, it is more sustainable than traditional framing lumber because it is made from smaller trees, which reduces the impact on the environment.
3. How is 2x8 LVL span sized?
The size of 2x8 LVL span is determined by its height, width, and length. The most common height for 2x8 LVL span is 7 ¼ inches, and the most common width is 1 ¾ inches. The length of the beam can vary depending on the span of the structure it is supporting. 2x8 LVL span is available in lengths up to 60 feet, making it a versatile option for many different types of construction projects.
4. How is 2x8 LVL span installed?
2x8 LVL span is typically installed using a crane or other heavy equipment. The beam is placed into position on top of the supporting walls or posts, and then secured into place using special hangers, bolts, or screws. It is important to follow the manufacturer's installation instructions to ensure that the beam is installed correctly and can support the required load.
5. What is the maximum span for 2x8 LVL span?
The maximum span for 2x8 LVL span depends on several factors, including the load that it will be supporting, the spacing of the supporting walls or posts, and the type of hangers or connectors that will be used to secure the beam. In general, 2x8 LVL span can span up to 16 feet for residential floor and roof applications, and up to 24 feet for commercial or industrial applications.
6. What is the load capacity of 2x8 LVL span?
The load capacity of 2x8 LVL span depends on several factors, including the span, the load that it will be supporting, and the type of hangers or connectors that will be used to secure the beam. In general, 2x8 LVL span can support a live load of 40-60 pounds per square foot, which is sufficient for most residential and commercial applications.
7. How much does 2x8 LVL span cost?
The cost of 2x8 LVL span varies depending on the size, length, and manufacturer of the beam. In general, 2x8 LVL span is more expensive than traditional framing lumber, but it is also stronger and more stable, which can result in cost savings in other areas of the construction project.
8. What are the installation requirements for 2x8 LVL span?
The installation requirements for 2x8 LVL span will vary depending on the manufacturer and the specific application. In general, it is important to follow the manufacturer's instructions for installation, including the type of hangers or connectors that will be used to secure the beam, the spacing of the supporting walls or posts, and the type of fasteners that will be used.
9. Can 2x8 LVL span be used for outdoor applications?
2x8 LVL span is designed for use in dry, indoor applications. It is not recommended for use in outdoor applications where it will be exposed to moisture or other weather conditions. If you need a beam for an outdoor application, you should consider using a different type of engineered wood product or a traditional framing lumber that has been treated to withstand outdoor conditions.
10. How can I find a qualified installer for 2x8 LVL span?
To find a qualified installer for 2x8 LVL span, you should contact your local building department or a structural engineer in your area. They can provide you with a list of qualified contractors who have experience with installing engineered wood products. It is important to hire a qualified installer to ensure that the beam is installed correctly and can support the required load.
In conclusion, 2x8 LVL span is a strong, stable, and sustainable option for supporting heavy loads over long distances. It is important to follow the manufacturer's installation instructions and hire a qualified installer to ensure that the beam is installed correctly and can support the required load. If you have any questions or concerns about using 2x8 LVL span in your construction project, you should contact a structural engineer or other qualified professional for guidance.
