Yeah and this based on what I have read and seen and been told. If you can wrap the plate onto two different planes, you add siginificant strength to the structure and lessen the chance that the plate will punch through the floor or simply tear away from the floor.

Another solution if you cannot get the plate to wrap onto two different planes is to drill a hole in the center of the plate, maybe 1/2" in diameter, then weld the center of the plate to the floor as well. Ideally this rosette weld (I think that is the proper term?) would fall directly under where the bar lands. This increases the weld area and also helps to keep the plate from pulling on the floor solely at the perimeter of the plate and acts to distribute load on the entire area of the floor under the plate, not just the edges.
