1. What is Wood Floor Load Capacity?

Wood floor load capacity refers to the maximum weight per square foot that a wood floor system can safely support. It's determined by factors including the size and strength of structural members and their span.

2. How Does the Calculator Work?

The calculator uses the wood floor load equation:

\[ Load_{psf} = \frac{Size\_factor \times Strength}{Span\_ft} \]

Where:

Explanation: The equation calculates the safe distributed load capacity based on member properties and span length.

3. Importance of Load Calculation

Details: Accurate load capacity calculation is crucial for structural safety, preventing floor failures, and meeting building code requirements.

4. Using the Calculator

Tips: Enter the size factor (based on member dimensions), material strength in psi, and span length in feet. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Where do I find the size factor?
A: Size factors are typically found in engineering tables based on the cross-sectional dimensions of the floor joists.

Q2: What are typical strength values for wood?
A: Strength varies by wood species and grade - common values range from 900 psi (softwoods) to 2000 psi (hardwoods).

Q3: How does span affect load capacity?
A: Longer spans significantly reduce load capacity - doubling the span approximately halves the capacity.

Q4: Does this account for safety factors?
A: This provides theoretical capacity - actual design loads should include appropriate safety factors per building codes.

Q5: Can this be used for other materials?
A: The basic principle applies, but specific factors differ for steel, engineered wood, or other materials.
