Treatment of torsion of reinforced concrete beams in ...

Design for torsion unlike design for shear, bending, and axial force, which have been perfected over the years, has not attracted as much attention and is in a rather weaker state. This paper reviews the provisions of the current standards in relation to torsion of reinforced concrete beams and highlights their weaknesses and strengths.
