The current design procedure for torsion is based on the following assumptions: § Concrete strength in torsion is neglected. § Torsion has no effect on shear strength of concrete. § Torsion stress determination is based on thin-walled tube, space truss analogy. Both solid and hollow members are considered as tubes before and after cracking, and
