Current Topic:
Beam Loading Question

Perhaps the columns are resting on a slab cement floor?  This would act to spread the load to the slab then to the the ground below, or to the wal bearing footers.  I am not familiar with the codes as to whether a footing directly under the column four feet below the ground level is required.

But the columns are necessary to support the load from above - your 1 inch deflection over 15.5 feet jumps to over a  foot  deflection for a 28 foot span, assumming the entire flooer load is carried by the one beam and the adjacent bearing walls.  are there other support beams?
