Question

Select the most economical A992 steel interior building column based upon the
following compressive load design criteria:
Live Load:
2nd Floor: 100 psf
Mezzanine: 50 psf
Roof: 50 psf
Dead Load:
2nd Floor: 60 psf
Mezzanine: 300 psf
Roof: 20 psf
The 1st floor contributes no load to the column, as the slab-on-grade construction
passes loading directly into the subsurface below. The mezzanine is a storage
area, located between the 2nd floor and the roof, and for design purposes,
generates a loading condition similar to the 2nd floor loading. The tributary area
of loading for the interior column is equal to 15 feet x 20 feet. The column is 20
feet tall between the floor slab and the second floor, and the end conditions are
pinned at the top and fixed at the bottom.
