The transverse torsional reinforcement in RCC beams can be provided as -

a) Like ties .

The reason of occurrence of torsion in beam is rotation of secondary beam end so it create torsion into primary beam.

Is 456 give guidelines to find equivalent shear which Incorporate torsional moment and if shear strength of concrete is less than 0.6 times shear stress than no need to provide shear reinforcement.

If shear strength exceed shear stress provide shear reinforcement to resist equivalent shear.
