Two way slab on top of steel construction

I have three levels of a 9" slab with perimeter beams on top of steel construction. I am trying to check the size of the steel framing below. The values that RAM FRAME is using is not realistic for the actual loads for steel design. A typical interior column with a bay of 31'x32'-4", based of trib area is around 150 kips per floor in self weight. RAM FRAME shows 150 kips for all three levels. I know FRAME uses finite elements to distribute the loads but, it seems to be way off. Is there a way to get realistic values so i can size the steel and foundations?
