1. A column is made of two Channel sections as shown. They are latticed together by light diagonal bracing. The bracing prevents them from moving independently of each other however it does not itself add to the inertia properties. The column is 480" long and is Ball and Socket supported at each end. The column is A36 steel with E = 29,000 ksi. Determine the largest axial compressive load that can be supported with a safety factor of 2. Lacing bars C10 x 15.3 shapes aligned toe-to-toe 8.5 in.
