Beam Weight Calculation Formula
The weight of a structural beam is calculated using the fundamental formula:
Weight = Cross-sectional Area × Length × Material Density
Specific Formulas by Beam Type:
- I-Beam: Area = (2 × Flange Width × Flange Thickness) + ((Height - 2 × Flange Thickness) × Web Thickness)
- Rectangular Tube: Area = (Height × Width) - ((Height - 2 × Thickness) × (Width - 2 × Thickness))
- Square Tube: Area = (Side²) - ((Side - 2 × Thickness)²)
- Circular Tube: Area = π × (Outer Radius² - Inner Radius²)
