What this calculator helps you find
A continuous beam has more than two supports and is generally statically indeterminate. Add all supports at their actual positions in the general calculator. The model uses stiffness-based analysis, so elastic modulus and second moment of area can affect how reactions distribute in indeterminate cases.
Relevant formula
Worked example
For a beam extending across three supports, add the interior support before applying loads. Compare the support reactions and negative moment over the interior support with the positive span moments.
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.
