Tapered beams are widely used in both civil and industrial engineering, where such elements allow for a more efficient distribution of material in comparison to prismatic beams.

Abstract
Tapered beams are widely used in both civil and industrial engineering, where such elements allow for a more efficient distribution of material in comparison to prismatic beams. Taper affects the stress distribution in a beam. In particular, the distribution of shear stresses may be completely different from that observed in prismatic beams. Strange as it may seem, this issue is normally not taken into account by standard design procedures based on beam element models, with consequent possible under- or over-estimation of the stress states acting in a real structure. The present work aims at shedding light on this question by studying the effects of taper on shear stresses in a purposely simplified problem.
