Are continuous beams designed for bending moment at column center or column face in RCDC software?

For Example, dimension of a column is 1200/1400/1600mm sagging moment at column center is much greater than column face (which is 600/700/800mm away from center of column).

In the above snap, moment at center of column(1200mm*1200mm) is ~6140kN-m. If we move to face of column moment is ~5100 kN-m.

So why RCDC designs a beam for 6140kN-m instead of  ~5100 kN-m.
