Chapter 18, Problem 18.10P
Use Euler’s formula and a factor of safety of 2.5 to design a W14 structural steel wide flange column to support an axial load of 350 kips. The length of the column is 34 ft and its ends are pin-connected.

(a) Explain FIVE (5) factors that may influence the optimum column design under an axial compressive load.
(b) A 3.6 m long pin-ended column is formed from an A-36 steel circular hollow section with an outer diameter of 75 mm. Determine the minimum thickness, t (to the nearest integer in mm) of the circular hollow section so that the column can safely support the load of 200 kN without buckling. If the outer diameter of the steel circular hollow section is reduced to 62 mm and the ends are pinned-fixed supported, analyse whether the column with the same applied load and the sectional thickness computed above will cause a buckling failure.
An aluminum tube of length 0.01R (m) is used as column (fixed at both ends) carrying an
axial load of 1.333R (N). If the outer diameter of the tube is 0.06R (mm),compute the inner
diameter that would provide a factor of safety of 2 against buckling. Use E = 70 GPa for aluminum.
Note R=993
The column AB is connected to the frame through pin-joints as shown in Figure 1.
There exists a lateral support in the column at C only in the weak y-direction. Check if
a 200UB18.2 section of Grade 300 steel has adequate strength to be used as column
AB. If not, select an alternative UB section that has adequate strength.
