8. A "rigid" horizontal beam AD is supported by two pin-ended columns as shown in the figure below. The columns have the same cross-sectional dimensions and are made of the same material (i.e., same I and same E). Determine (a) an expression for the load Wa that will cause elastic buckling of one of the columns, and indicate which column will buckle first (b) an expression for load W, that would cause the second column to buckle also. Assume that the force in the column that buckles first remains constant after that column buckles.

A steel column carries an axial load of 819 kN and a moment of 63 kN-m at the top and moment at the bottom which is only70% of the moment at the top. The two moments are in opposite direction and applied about the x-axis and the steel section has the following properties: A = 13172 mm2 rx is 109 mm ry = 94 mm Sx = 1200 x 103 mm3 K = 1.0 L= 3.6 m E = 200,000 Mpa Fy = 248 Mpa Use NSCP specification for compressive stress and Fb =148 Mpa. Determine the Compressive Stress if Axial load only existed.
