How to Use the LVL Beam Spans Table?

The LVL (Laminated Veneer Lumber) Beam Spans Table is a crucial tool for construction, helping builders determine the appropriate beam size for specific load conditions. Here’s a step-by-step guide on how to use it effectively.

1. Understand the Table Layout

The LVL Beam Spans Table is typically divided into columns and rows. The columns represent different LVL sizes, while the rows list span lengths and load conditions. Familiarize yourself with the layout to accurately read the information.

2. Identify the Load Type

Before referencing the table, determine the type of load the beam will support. The loads can be categorized into:

• Live Load: Temporary loads like furniture and people.
• Dead Load: Permanent loads like the weight of the structure itself.
• Other Loads: Any additional loads that may occur like snow or equipment.

3. Determine the Required Span

Next, measure the distance that the LVL beam needs to cover without support. This is known as the span. Be sure to consider any factors such as obstructions or irregular spacing that may affect the measurement.

4. Select the Correct LVL Size

Using the determined load type and span, go to the corresponding row and column in the table. The intersections will provide span ratings for different LVL sizes. Depending on your load conditions, you may need to select a larger beam size if the load is higher or the span is longer.

5. Verify Structural Integrity

Once you’ve chosen the appropriate LVL size, it’s essential to double-check that the beam complies with local building codes and regulations. Consult with an engineer if needed, especially for large structures or high loads.

6. Consider Installation Requirements

The table often doesn't encompass all installation requirements, such as connections, supports, and fire ratings. Ensure you follow proper installation practices and guidelines to maintain safety and functionality.

Common Questions about LVL Beam Spans Table

Here are some frequently asked questions related to the LVL Beam Spans Table.

1. Can I use the LVL Beam Spans Table for different types of wood?

No, the LVL Beam Spans Table is specifically designed for LVL products. Other wood types may have different structural properties and require their own span tables.

2. What if my span is not listed in the table?

If your span is not listed, it is advisable to round up to the next listed span or consult a structural engineer to assess the situation properly.

3. Is it safe to add additional loads on LVL beams?

Adding extra loads can affect the beam’s performance. It is essential to consult the span table and, if necessary, seek professional advice to ensure safety.
