You would need to know whether the ceiling joists ran parallel or perpendicular to the 1/2 wall.
You should be able to determine this pretty easily.
You can try pushing the ceiling up next to the column on all 4 sides( about a foot away) and see where the beam is. Look in the basement and attic and see how those joists run.
You can cut a hole in the ceiling and look.
