Ultimate Free Beam Calculator – Shear / Bending / Deflection

Written by Corey Rasmussen in Calculators,Stress Flow / Hand Calcs Last Updated March 24, 2023

This free beam calculator gives you the advantage to calculate a wide variety of beam types and loads. Add as many loads on a beam as you want. It automatically calculates shear load, moment and deflection.

6 Beam Types

  • Cantilever
  • Cantilever and Guided
  • Simply Supported
  • Fixed (Statically Indeterminate)
  • Supported and Fixed (Statically Indeterminate)
  • Simply Supported with Overhang

9 Load Types

  • Point Loads
  • Moment Loads
    • On Span
    • At End
  • Distributed Loads
    • Constant
    • Increasing
    • Decreasing
    • Pyramid
End Conditions:
Beam Length (in):
Young's Modulus (ksi):
Moment Of Inertia (in4):

Notes:
  • Downward applied loads and deflections are positive.
  • Upward shear loads are positive.
  • Concave moment results are positive.
  • Yellow highlights are values of L/360 or greater.
  • Red highlights are values of L/240 or greater.
  • Combinations of load cases may cause the maximum deflection to occur in an unexpected location. Adding a low magnitude point load at multiple locations will allow you to find the maximum deflection
