1. What is the Glulam Span Formula?

The Glulam Span formula calculates the maximum span length for a glued laminated timber beam based on its moment capacity and the applied load. This formula is essential for structural engineering and construction planning.

2. How Does the Calculator Work?

The calculator uses the Glulam Span formula:

Where:

• \( M \) — Moment capacity of the beam (lb-ft)
• \( w \) — Applied load per unit length (lb/ft)
• \( Span \) — Maximum span length (ft)

Explanation: The formula calculates the maximum span by considering the beam's ability to resist bending moments under a specific load.

3. Importance of Span Calculation

Details: Accurate span calculation is crucial for ensuring structural integrity, safety, and compliance with building codes in timber construction projects.

4. Using the Calculator

Tips: Enter the moment capacity in lb-ft and the load in lb/ft. Both values must be positive numbers to calculate a valid span.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for input values?
A: The calculator expects moment capacity in lb-ft and load in lb/ft for consistent results in feet.

Q2: Does this formula account for safety factors?
A: No, this is the theoretical maximum span. Always apply appropriate safety factors according to local building codes.

Q3: Can I use this for other beam materials?
A: While the formula is general, specific material properties and design considerations may vary for different beam types.

Q4: What if my beam has multiple load points?
A: This formula is for uniformly distributed loads. Consult a structural engineer for complex loading conditions.

Q5: How accurate is this calculation?
A: This provides a theoretical maximum span. Actual design should consider deflection limits, connection details, and other structural factors.
