Yes this has been in ACI for at least last 25 years.
Footings and slabs are exempted unless: Vu >½ ФVc,

Subject: about ACI


ACI 318 - States that a minimum area of shear reinforcement shall be provided in all reinforced concrete flexural members (prestressed and nonprestressed) where factored shear force Vu exceeds 1/2 x Phi x Vc;

(a) Slabs and footings;

Do I interpret this to mean that in slabs and footings minimum shear reinf. is not required unless Vu>Phi x Vc?
