## How to Calculate Beam Loading
### Formula
**Load per Linear Foot = (Dead Load + Live Load) × Tributary Width**
**Total Load = Load per Linear Foot × Span**
**Support Reaction = Total Load / 2** (for a uniformly loaded simple beam)
Tributary width is the distance from the beam centerline to the midpoint between the beam and the next parallel support on each side. This calculation assumes a uniformly distributed load on a simply supported beam.

Esempio Risolto
A 16 ft beam with 8 ft tributary width, 15 psf dead load, 40 psf live load.
- Total load = 15 + 40 = 55 psf
- Load per linear foot = 55 × 8 = 440 lbs/ft
- Total beam load = 440 × 16 = 7,040 lbs
- Reaction per support = 7,040 / 2 = 3,520 lbs
