Document Type: Journal Paper


The design of beams in which torsion occurs, usually due to an eccentricity of the applied load, is either crudely approximated or, if studied accurately, involves the use of hyperbolic functions. This paper shows how simple beam formulas can be extended to deal with torsion and how, by considering torsional rigidity and torsion-bending rigidity separately, results of acceptable accuracy can be obtained.
