1. A round column is to be designed with DL = 600 KN, LL = 800
KN, fc’ = 20.7 MPa, fy = 345 MPa. Use ?? = 0.02, 25 ?? ∅ ???? ????,
??? 10 ?? ∅ ???. USE 1.2 DL + 1.6 LL USD AND WSD. provide

Design a rectangular tied column for a DL = 1000 KN and a LL =
1350 KN. It also carries a ???????? = 20 KN m and ???????? = 40 ??.
?ℎ? ?? ′ = 27.6 ???, ?? = 414 ???.
W shape column must support a axial load (DL=500 kips y LL=
300 kips). The element is 30 ft length and braced in the y
direction at 14 ft from the column base. The end support conditions
are (fixed/pinned). Justify the material’s selection. verify
slenderness and local buckling and Select the lightest
section
Design a square interior column footing for a 15-in. square tied
interior column that supports a dead load of 160 kips and live load
of 180 kips. The column is reinforced with eight # 8 bars, also,
the base of the footing is 6 ft below the grade line, the soil
weight is 100 lb/ft3, the concrete weight is 150 lb/ft3, f’c =
4,000 psi, fy = 60,000 psi and qa = 4 kip/ft2.
QUESTIONS:
Design a square column footing for a 20-in. square
tied interior column that supports loads of DL (170) k and Live
load LL (210) k. The column is reinforced with eight No 8 bars, the
bottom of the footing is 5 foot below final grade, and the soil
weighs 100 lb. /ft3 the allowable soil pressure is 4 w ksf. The
concrete strength is 4,000 psi and the steel is Grade
60.

A column is to support a statue concentrically that weighs 200
kN. The cross section of the column is a regular hexagon with a
hole in its center. The diameter of the hole is 75mm. If the stress
in the column is limited to 250 MPa, what is the measure of one
side of the hexagon? Answer should be in mm.
