Abstract:
Formulas, accompanied by examples, are presented for determining torsional shear stresses, diagonal tensile stresses, and angle of rotation for plain rectangular and circular beams, T-, L-, and l-beams, with flanges, and for rectangular box sections. (Most of these equations are included in the new Australian building code.) Examples and formulas are also given for determining the amount of torsion reinforcement required for both circular and rectangular beams. The relative qualifications and limitations of these formulas are discussed. The final part of the paper discusses maximum permissible stresses in torsion, combined torsion and shear, and combined torsion and bending. An annotated bibliography on the torsional strength of concrete is appended.
