1. What is Deck Beam Span Calculation?

Deck beam span calculation determines the maximum allowable distance between supports for deck beams according to the Ontario Building Code. Proper beam sizing is essential for structural integrity and safety of deck constructions.

2. How Does the Calculator Work?

The calculator uses span tables from the Ontario Building Code:

Where:

• Beam Size — Dimensions of the beam in inches
• Load — Expected load in pounds per square foot (psf)
• Span Tables — Pre-calculated values from Ontario Building Code

Explanation: The calculation references standardized tables that account for wood species, grade, and Ontario-specific building requirements.

3. Importance of Proper Beam Sizing

Details: Correct beam span calculation ensures deck safety, prevents sagging, and complies with Ontario building regulations. Undersized beams can lead to structural failure.

4. Using the Calculator

Tips: Enter beam size in inches and expected load in psf. Consult the Ontario Building Code for specific wood species and grade requirements.

5. Frequently Asked Questions (FAQ)

Q1: What is the typical load requirement for Ontario decks?
A: Ontario Building Code typically requires decks to support at least 40 psf for residential applications, but specific requirements may vary.

Q2: How does wood species affect beam span?

Q3: Are there different requirements for different Ontario regions?
A: The Ontario Building Code applies uniformly across the province, but local municipalities may have additional requirements.

Q4: How often should deck beams be inspected?
A: Decks should be inspected annually for signs of wear, and beams should be checked for deflection, cracking, or rot.

Q5: Can this calculator be used for commercial decks?
A: Commercial decks typically have higher load requirements. Always consult the Ontario Building Code and a structural engineer for commercial applications.
