LvL Span Table Calculator

What is a LVL Span Table Calculator?

A LVL span table calculator is a tool that helps builders and engineers determine the appropriate size (depth and width) and maximum span of LVL beams or joists for a given load and other factors, such as species and grade of LVL material.

It ensures that the structural elements meet building code requirements and provide adequate support for the intended loads.

Why Use a LVL Span Table Calculator?

Using an LVL span table calculator is crucial for structural integrity and safety.

It helps avoid under-sizing (which could lead to structural failure) or over-sizing (which could be unnecessarily expensive).

By inputting relevant parameters, you can find the optimal LVL beam size and span length for your specific construction project.

How to Use an LVL Span Table Calculator:

1. Gather Information:
   • Uniform Load: Determine the expected load per linear foot (e.g., in pounds per foot, plf) that the LVL beam or joist will support.
   • LVL Species: Select the appropriate LVL species (e.g., SPF, Douglas Fir) based on local availability and requirements.
   • LVL Size: Choose the initial LVL size options available (e.g., 2x6, 2x8, 2x10).
   • Span Length: Measure the distance over which the LVL beam or joist will span (e.g., in feet).
2. Access a Span Table:
   • Manufacturers of LVL products typically provide span tables specific to their products. These tables offer recommendations based on load, species, size, and other factors.
   • You can access these tables in product literature, engineering manuals, or on the manufacturer's website.
3. Use the Calculator:
   • Enter the gathered information into the span table calculator, such as load, species, size, and span length.
   • The calculator will provide recommendations on the suitable LVL size and maximum allowable span for your specified conditions.
4. Check Local Building Codes:
   • Ensure that the calculated LVL size and span length comply with local building codes and regulations. Codes may impose additional requirements or restrictions.
5. Consult with an Engineer:
   • If your project is complex or if you have any doubts about the calculations, it's advisable to consult with a structural engineer or architect. They can provide professional guidance and ensure the structural elements meet safety standards.

Example (Simplified):

Suppose you have a uniform load of 1000 pounds per foot (plf), you're using SPF LVL, and you want to span 12 feet.

You consult the manufacturer's span table and find that for these conditions, a 2x10 LVL beam is recommended.
