An ASTM A992 W-shaped column is used to carry an axial dead load of 140 kips and a live load of 420 kips. The column is 30 ft long and is pinned at the top and fixed at the bottom. Limit the size to a nominal 14-in shape. Assume the column is laterally braced at the midpoint about the y-axis. Use LRFD. What is the governing slenderness ratio of the chosen W-shaped column? Select one: a. 50.81 b. 48.65 c. 34.05 d. 72.58
