Resumen de A review of the Wood and Armer equations for torsion in bridge slabs

Eugene J. OBrien, Dermot O'Dwyer

• The ‘Wood and Armer’ equations are well established as a means of accounting for torsional moments in bridge slabs. In this article, a potential source of misinterpretation of the original equations is identifi ed and corrected. The misinterpretation is shown not to have signifi cant implications for design, but may be of consequence where the Wood and Armer equations have been used for assessment. A number of other inconsistencies are identifi ed and a revised set of equations is proposed.
