Select the most economical A992 steel interior building column based upon thefollowing compressive load design criteria:Live Load:2nd Floor: 100 psfMezzanine: 50 psfRoof: 50 psfDead Load:2nd Floor: 60 psfMezzanine: 300 psfRoof: 20 psfThe 1st floor contributes no load to the column, as the slab-on-grade constructionpasses loading directly into the subsurface below. The mezzanine is a storagearea, located between the 2nd floor and the roof, and for design purposes,generates a loading condition similar to the 2nd floor loading. The tributary areaof loading for the interior column is equal to 15 feet x 20 feet. The column is 20feet tall between the floor slab and the second floor, and the end conditions arepinned at the top and fixed at the bottom.
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.
