Background
Clause 9.2.2 Minimum structural integrity reinforcement
The summation of the area of bottom reinforcement connecting the slab, drop panel, or slab band to the column or column capital on all faces of the periphery of a column or column capital shall be not less than,
\[ A_{s.min} = \frac{2N^*}{\Phi f_{sy}} \]
in which N* is the column reaction from the floor slab at the ultimate limit state. Integrity reinforcement shall not be required if there are beams containing shear reinforcement and with at least two bottom bars continuous through the joint in all spans framing into the column.
