Maximum Floor Live Load Capacity Calculator
This calculator estimates the maximum live load a floor can support without excessive deflection or failure. It is based on span, stiffness, modulus of elasticity, and a correction factor. Engineers and architects use it to assess floor safety under dynamic loads like people, furniture, or equipment.
Calculate Maximum Live Load on Floor Structure
Live Load Capacity Formula
Where
- $$w$$ β maximum floor live load
- $$s$$ β span of the floor
- $$k_h$$ β stiffness or floor constant (empirical)
- $$E$$ β modulus of elasticity of the floor material
This empirical formula helps engineers validate whether a specific flooring design can sustain intended live loads. Itβs particularly relevant for suspended floors in residential, commercial, and industrial buildings. Ensure units are consistent to get accurate results (e.g., kN/mΒ², psi, etc.).
