The 18x40's @3' do look odd- High density filing stacks for all the college's paperwork maybe?

Mike, you are correct - W18x40 @ 3' O.C. with 30 shear studs per beam(holy cow!). Of course maybe the ordinal plan was to drive a train on that floor?

The original floor beams appear to be W18x40, at least to my poor eyes.
