A single compression member of 30 ft effective length is
obtained by connecting two C6 x 13 steel channels with lacing bars
as shown in Figure 1. Determine the distance d for this
cross-section corresponding to the most efficient design against
buckling (the most efficient design occurs when the resistance to
buckling is equal in both planes of symmetry).

2. Verify that a built-up ASTM A572 Grade 50 (Fy - 345 MPa) column with PL 205 x 25 mm flanges and PL 380 * 6 mn web is sufficient to carry a dead load of 300 kN and live load of 900 KN in axial compression. The column, having an unbraced length of 8 meters, is braced at the midpoint about the weak axts, the ends are pinned in both axes. (Use ASD, 15 pts)
