Therefore slenderness of internal columns only needs to be checked.

Clearly, this will normally be the case for multi-bay frames unless the edge columns carry large cladding loads.

For a horizontally loaded flat slab frame determine the stiffnesses of the frame and thus the effective lengths of the columns using half the slab stiffness. Consider the centre column from foundation to first floor.
