Question #2 (20 points) A (a) A Composite column made of reinforced concrete was constructed on a very rigid foundation. The column was constructed at 25 °C and in this temperature, there was no stress in the system. The column is exposed to axial loading (or stress) of 2000 psi as shown in the picture. The column has a thickness of 8 in, a width of 3 in, and a length of 13 ft. Six #6 longitudinal bars (each has...
