NOTE: The interior column strip is defined by one quarter of the smaller of 1 and 2 each side
of the column centerline. The exterior column strip is bound by the slab edge and one
quarter of the smaller of 1 and 2 from the column centerline. The middle strip is the
remaining width between column strips.
