2. Use compression design tables in Section 4 of the AISC manual to choose the lightest section for each of the following scenarios. Avoid shapes that are slender for compression. Assume the given KL is controlling. For your answer, include not only the member size, but also its capacity and weight per linear foot. (For example, a complete answer would be something like this: HSS 6 x 6 x .25, QPn=109 kips, Self Weight = 19.02 plf) a. Double Angle (Equal Legs), KLy=30 ft, Pu=195 kips (Fy=36 ksi) (Assume adequate number of connectors): b. Square HSS, KLy=20 ft, Pu=800 kips (Fy-50 ksi): c. W-Section, KLx=25 ft, Pu=1050 kips (Fy=50 ksi): d. Rectangular HSS, KLy=15 ft, Pu=300 kips (Fy=50 ksi): 2.
