A built-up section consisting of W 350 x 90 with two 12 – mm plates welded to form a box section as shown in figure. The section is used as a column 10 meters long. The column is fixed at both ends, and braced at mid height about the weak axis (Y-axis). Use Fy = 248 MPa. a. Determine the effective slenderness ratio of the column with respect to lateral buckling about the x-axis. b. Determine the effective slenderness ratio of the column with respect to lateral buckling about the y-axis. c. Determine the axial load capacity of the column in kN.
