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

Tributary area = half span on each side of column

Building Parameters

Live load: 2.5 kN/m², Dead load allowance: 1.5 kN/m²

Additional Loads

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
