What this calculator helps you find
Support reactions come from equilibrium and the compatibility conditions of the beam model. Enter the support positions and every point load, distributed load, and applied moment before interpreting the reaction values.
Relevant formula
ΣFy = 0 and ΣM = 0
Worked example
A 10 m simply supported beam carrying a 5 kN/m uniform load has 50 kN total downward load. By symmetry, each support reaction is 25 kN upward.
Use results responsibly
Use this tool for idealized, static two-dimensional analysis and for checking calculations. Confirm units, sign conventions, supports, material properties, and applicable design standards before using results in a project. Review the assumptions and limitations and validation records.
