4.4-2 A W21 × 101 is used as a compression member with one end fixed and the other end free. The length is 10 feet. What is the nominal compressive strength if Fy = 50 ksi? Note that this is a slender-element compression member, and the equations of AISC Section E7 must be used.

Section E7 must be used.

4.6-2 A 15-foot long column is pinned at the bottom and fixed against rotation but free to
translate at the top. It must support a service dead load of 100 kips and a service live
load of 100 kips.
a. Select a W12 of A992 steel. Use the column load tables.
1. Use LRFD.
2. Use ASD.
b. Select a W16 of A992 steel. Use the trial-and-error approach covered in Section 4.6.
1. Use LRFD.
2. Use ASD.
