Beam Load Calculator
Calculate bending moments, shear forces, and deflections for structural beams. Supports simply supported, cantilever, and fixed-end conditions with visual moment and shear diagrams.
Steel: 200,000 MPa, Concrete: ~25,000 MPa
Required for deflection calculation
| Section | Depth (mm) | Capacity (kN·m) |
|---|---|---|
| UB 203x133x25 | 203 | 50 |
| UB 254x146x31 | 254 | 80 |
| UB 305x165x40 | 305 | 120 |
| UB 356x171x51 | 356 | 170 |
| UB 406x178x60 | 406 | 230 |

Positive moment = tension at bottom (sagging)
Positive shear = upward force on left of section
Left Reaction (R₁)
60.00 kN
Right Reaction (R₂)
60.00 kN
Notes:
- Results are for preliminary design only
- Verify with detailed structural calculations
- Consider load combinations per applicable code
- Deflection limit typically L/360 for floors, L/240 for roofs
