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.

Free structural engineering spreadsheets for beam design have been provided for use in excel, located under each beam.

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