A steel column carries an axial load of 787 kN and a moment of 69 kN-m at the top and moment at the bottom which is only 70% 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 = 12974 mm2 rx= 109 mm ry=94 mm Sx = 1200 x 103 mm3

Question
A steel column carries an axial load of 787 kN and a moment of 69 kN-m at the top and moment at the bottom which is only 70% 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 = 12974 mm2 rx= 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. Questions: Determine the Compressive Stress if Axial load only existed.
