Assume that the floor between Beams B7 and B8 is supported
directly by these two beams only (not by Girders G2 and G3). Beam
B7 has a self-weight of 30 plf. The floor slab consists of a
4-in.-thick, normal-weight, reinforced concrete slab (unit weight =
150 pcf). An additional floor dead load of 15 psf is specified to
account for the weight of suspended utilities and fixtures. As an
exterior beam, B7 must also support one...

Design a square single column footing to support an 18 inch square interior column reinforced with 8-#10 bars. The column carries an unfactored dead load of 245 Kips that includes weight of soil and weight of footing and an unfactored live load of 20 feet below finished grade. The footing is 10 feet by 10 feet and is 30 inches thick. The allowable soil pressure is 5000 psf, fe' 4000 psi and fy 60000 psi. Concrete used shall be sand...
