About the Beam Load Calculator

Estimate reactions and bending for a simply supported beam under a uniformly distributed load or a load at the centre.

How to use the Beam Load Calculator

  1. Choose Distributed Load (UDL) or Center Point Load.
  2. Enter the Load and Beam Length (m).
  3. Press Calculate.

Formula and method

UDL: total load W = w × L, each support carries W ÷ 2 and the maximum moment is wL² ÷ 8. Centre point load P: each support carries P ÷ 2 and the maximum moment is PL ÷ 4.

Tips

  • This gives a first estimate only. A structural engineer must check real designs.

Frequently asked questions

What is a UDL?
A uniformly distributed load, spread evenly along the beam.
