How to Use the Beam Calculator
This advanced tool helps you determine the structural capacity of beams with precision:
- Select Material: Choose between steel, wood or concrete based on your project requirements
- Enter Dimensions: Input length in feet, width and height in inches
- Set Load: Specify uniform load in pounds per foot (lbs/ft)
- Calculate: Get instant moment capacity and deflection results
Beam Calculation Formulas
Our calculator uses industry-standard formulas:
- Moment Capacity: M = (σ × S) / safety factor
- Deflection: δ = (5 × w × L⁴) / (384 × E × I)
- Section Modulus: S = (b × h²) / 6 (rectangular cross-section)
- Moment of Inertia: I = (b × h³) / 12 (rectangular cross-section)
Why Calculate Beam Capacity?
Safety Assurance
Ensure structural integrity and prevent catastrophic failures by verifying beam capacity before construction.
Code Compliance
Meet building regulations and pass inspections with properly calculated structural elements.
Cost Efficiency
Optimize material usage to prevent over-engineering and reduce construction costs.
Frequently Asked Questions
Our calculator handles beam lengths up to 100 feet. For longer spans or specialized applications, consult a structural engineer.
The calculator provides professional-grade accuracy using industry-standard formulas. However, always consult an engineer for critical structural applications.
This version calculates uniform loads only. We're developing a point load calculator for future release.
