Question

The A992 steel column can be considered pinned at its top and bottom and braced against its weak axis at the mid-height (Figure 1) Part A Determine the maximum allowable force P that the column can support without buckling. Apply a F. S. = 2 against buckling. Take A = 7.4 (10-3) m² , 1x = 88.1 (10–6 m4, and 1y = 18.2 (10-6 m4.
