Determine the design compressive strength, ФР", based upon the flexural buckling for the built-up shape shown. The column length, L, is 28 ft. Assume that the components are connected in such a way that the gross section is fully effective and the ends of the column are fully fixed. Use ASTM A36 steel. Check and determine if the column conforms to the recommended slendernes ratio for compressive members. Assume a 1/2 in. gap between each angle. Problem 5 (20 points)...

If the column is 7 m long, fixed at one end and pinned at the other irn both planes, calculate the maximum slenderness ratio. The lacing joining the two channels does not affect its moment of inertia, but does make the channels act as one member. IIO 5.
