Question
A steel column carries an axial load of 785 kN and a moment of 72 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 = 12818 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:
From the Interaction Formula, compute the interaction value. Assume that the column is braced against joint translation (sidesway).
