According to ACI 18.13.2.3, if the column is designed assuming a fixed-end, it should satisfy ACI 18.13.2.2 requirements. Also, if hooks are required, longitudinal reinforcement resisting flexure should have 90-degree hooks near the bottom of the foundation with the free end of the bars oriented toward the center of the column.
According to ACI 18.13.2.4, transverse reinforcement of columns or boundary elements of special structural walls that have an edge within one-half the footing depth from an edge of the footing should be in accordance with ACI 18.7.5.2 , ACI 18.7.5.3 and ACI 18.7.5.4 (These 3 titles are explained in Transverse Reinforcement (CRD)). This transverse reinforcement should extend into the footing, mat or pile cap a length equal to development length, calculated for fy in tension, of the column or boundary elemant longitudinal reinforcement.
