Maximum floor live load capacity

This online calculator is designed to calculate the maximum stationary live load that the given floor can support.


psi or kPa

inches or mm

pci or MPa/m

psi or kPa


w = 257.876s ( kh / E ) ^ 0.5

  • w – maximum allowable stationary live load,
  • k – modulus of subgrade reaction,
  • h – thickness of slab,
  • s – allowable extreme fiber stress in tension,
  • E – modulus of elasticity.
