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.
