About Beam Load Calculations
Beam load calculations determine the maximum safe load a beam can support based on its material properties and dimensions.
Load Capacity Formula:
P = (σ × S) / (SF × L)
Where:
- P = Maximum load
- σ = Allowable stress
- S = Section modulus
- SF = Safety factor
- L = Beam length
Material Properties:
- Steel: 36,000 psi yield strength
- Concrete: 3,000 psi compressive strength
- Wood: 1,800 psi bending stress
- Aluminum: 35,000 psi yield strength
Support Conditions:
• Simply Supported: Both ends pinned
• Cantilever: One end fixed
• Fixed-Fixed: Both ends fixed
• Continuous: Multiple supports
Safety Factors:
• Residential: 1.5
• Commercial: 2.0
• Industrial: 2.5
• Heavy Duty: 3.0
Proper load calculations ensure structural safety and prevent beam failure under expected loading conditions.
