1. What is the Floor Load Equation?

The floor load equation calculates the total load per linear foot (plf) that a beam must support based on the live and dead loads per square foot (psf) and the spacing of the beams.

2. How Does the Calculator Work?

The calculator uses the floor load equation:

Where:

• \( w \) — Beam load (plf)
• \( live \) — Live load (psf)
• \( dead \) — Dead load (psf)
• \( spacing \) — Beam spacing (ft)

Explanation: The equation converts distributed floor loads (psf) to a linear load (plf) that each beam must support based on their spacing.

3. Importance of Beam Load Calculation

Details: Accurate beam load calculation is crucial for proper structural design, ensuring beams can safely support the intended loads without excessive deflection or failure.

4. Using the Calculator

Tips: Enter live and dead loads in psf, and beam spacing in feet. All values must be valid (loads ≥ 0, spacing > 0).

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between live and dead loads?
A: Dead loads are permanent (structure weight), while live loads are temporary (people, furniture).

Q2: What are typical values for floor loads?
A: Residential: Live 40 psf, Dead 10 psf. Commercial: Live 50-100 psf, Dead 15-30 psf.

Q3: How does beam spacing affect the load?
A: Wider spacing means each beam supports more area, increasing its load proportionally.

Q4: Are there code requirements for floor loads?
A: Yes, building codes specify minimum live loads based on occupancy type.

Q5: What other factors affect beam design?
A: Span length, material properties, deflection limits, and load duration factors.
