Question
A steel column 3.6m long Is pin connected at the top and bottom and is a part of
a frame subjected to buckling and sidesway. It carries an axial load of 800 kN
and a moment of 70 kN-m at the top and a moment at the bottom which is
90% of the moment at the top.

1. Compute the axial compressive stress if axial load only existed
2. Compute the bending stress if bending moment alone existed.
3. Compute the interaction value of both axial and bending stresses
