Beam Design Formulas

Simply select the picture which most resembles the beam configuration and loading condition you are interested in for a detailed summary of all the structural properties. Beam equations for Resultant Forces, Shear Forces, Bending Moments and Deflection can be found for each beam case shown. Handy calculators have been provided for both metric and imperial beam design and assessment.

Structural engineering spreadsheet collection for beam design using excel are available for purchase and can be found under each beam type.

Additional information regarding engineering beam design theory and the assumptions that have been made can be found Here.
