Enter the dimensions and load specifications into the calculator to determine the maximum span of your glulam beam.

Glulam Beam Span Calculation Formula

The following formula is used to calculate the maximum span of a glulam beam. 

Span = (Width * Height^2) / (Length * Load)

Variables:

  • Span is the maximum span of the glulam beam (ft)
  • Width is the width of the beam (in)
  • Height is the height of the beam (in)
  • Length is the length of the beam (ft)
  • Load is the load applied to the beam (psf)

To calculate the span, multiply the width by the square of the height, then divide by the product of the length and the load.

What is Glulam Beam Span Calculation?

Glulam beam span calculation refers to the process of determining the maximum span that a glulam beam can safely cover under a given load. This involves understanding the dimensions of the beam and the load it will bear. Proper span calculation ensures the structural integrity and safety of the construction project.

How to Calculate Glulam Beam Span?

The following steps outline how to calculate the span using the given formula.

  1. First, determine the dimensions of the beam including its width, height, and length.
  2. Next, determine the load that will be applied to the beam.
  3. Use the formula from above: Span = (Width * Height^2) / (Length * Load).
  4. Finally, calculate the span by plugging in the values.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

Width = 6 in

Height = 12 in

Length = 20 ft

Load = 50 psf
