Question: Two C12 x 25 structural steel channels (each channel: A = 7.34 in?,1, = 144 in.ly = 4.45 in,i = 0.674 in) are used

Two C12 x 25 structural steel channels (each channel: A = 7.34

Two C12 x 25 structural steel channels (each channel: A = 7.34 in?,1, = 144 in*.ly = 4.45 in*,i = 0.674 in) are used for a column that is 35-ft long. Assume pinned connections at each end of the column and use E %3! %3D 29,000 ksi for the steel. Determine the total compressive load required to buckle the two members if: a. They act independently of each other b. They are latticed back-to-back as shown Lacing bars C12 25 C12-25 6 in.
