Column Load Calculator
Calculate axial loads on columns from tributary areas and floor loads. Includes load accumulation for multi-story buildings and preliminary column sizing recommendations.
Tributary area = half span on each side of column
Live load: 2.5 kN/m², Dead load allowance: 1.5 kN/m²
Finishes, partitions, MEP
Accessible roof: 1.5-4.0
Add weight of column throughout height
Enter building parameters to calculate column loads
Notes:
- Live load reduction per ASCE 7 / Eurocode 1
- Load factors: 1.35 (dead) + 1.5 (live) per Eurocode
- Column sizing assumes C30 concrete, ρ = 2%
- Beam loads, lateral loads not included
- Verify with detailed structural analysis
