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

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.
A 5-kN horizontal load acts on the column shown in Figure Q3 at
a location of 1.7 m above the ground level. 50 kN Elev. 0.0
GWT-Elev.-1.1 m Elev.-2.0 m_ Figure Q3 (1) Determine a suitable
footing size, using the following information: The site soil is
granular soil with an angle of friction 20°, a unit weight of
16.5kN/m (above the groundwater table) and a saturated unit weight
of 19.8 16.5kN/m3: Factor of safety FS-2.5; (2) If the horizontal

1) Select the lightest section to support a axial load (DL=700
kips y LL= 300 kips). The
element is braced, so LX= 22 ft and LY= 12 ft. The end support
conditions are:
a) (Fixed/pinned) and it is specified to use A572 gr. 60. (verify
slenderness and
local buckling)
b) (Fixed/Fixed) and you must use A-36
A short reinforced concrete column is subjected to a
1000 kN axial compressive load. The moduli of elasticity of plain
concrete and steel are 25 GPa and 207 GPa, respectively, and the
cross-sectional area of steel is 2% of that of the reinforced
concrete. Considering the column as a structural member made of a
composite material and subjected to load parallel to the steel
rebars, calculate the following:
a. the modulus of elasticity
of the reinforced concrete
b. the load...
