How far can a lvl beam span without support?

Calculating the Span of a LVL Beam Without Support

Laminated veneer lumber (LVL) beams are commonly used in construction to support heavy loads over long spans. The span of an LVL beam without support is determined by several factors including the type of LVL beam, the load it will carry, and the spacing of the supports.

Step 1: Determine the Type of LVL Beam

LVL beams come in different sizes and grades, each with its own load-carrying capacity. To determine the maximum span of an LVL beam without support, you need to know the type and grade of the beam you are using. This information can usually be found in the manufacturer's specifications.

Step 2: Calculate the Load on the Beam

The load that the LVL beam will carry is another important factor in determining its maximum span without support. You need to consider both the dead load (the weight of the beam itself) and the live load (any additional weight that will be placed on the beam) that the beam will support.

Step 3: Use a Span Table or Structural Engineer

Once you have determined the type of LVL beam and calculated the load it will carry, you can consult a span table provided by the manufacturer. This table will typically list the maximum span of the beam for various load scenarios. Alternatively, you can consult a structural engineer to calculate the maximum span based on the specific requirements of your project.

Step 4: Consider Support Spacing

The spacing of the supports that the LVL beam will sit on also plays a role in determining the maximum span without support. The closer together the supports, the shorter the span can be without additional support. Make sure to follow the manufacturer's recommendations for support spacing to ensure the structural integrity of the beam.In conclusion, the span of an LVL beam without support is determined by the type and grade of the beam, the load it will carry, and the spacing of the supports. By following these steps and consulting the appropriate resources, you can determine the maximum span of an LVL beam for your specific construction project.
