If shear stress is greater than 5kg/cm^2 then we use 12 legged stirrups and if it less than 5kg/cm^2 then we use 8 legged striups.

Footing essentially acts as a wide beam.

Normally, in combined footing, we do not provide shear reinforcement. If nominal shear strength exceeds permissible shear strength, then its depth is increased so that nominal shear strength is less than permissible shear strength.

However, Shear reinforcement is provided when nominal exceeds permissible shear strength. It depends on dia, stress & spacing of stirrups. It is not fair to say 8 or 12-legged.

If the shear stresses not more than 5 kg/cm^2 = 8 legged stirrups.

And If Shear stress more than 5kg/cm^2 = 12 legged stirrups.

If it >5 then 12.

If <5 then 8 stirrups.
