Two channels are welded at the tip of the flanges to form a box column.
Properties of each channel
A = 5485 mm2
tw = 10 mm
d = 250 mm
bf = 100 mm
tf = 15 mm
Ix = 52 x 106 mm4
ly = 5 x 106 mm4
Distance from centroidal y-axis of the channel to the outer face of the web, x = 29 mm. Column height = 4 m. and effective length factor K = 1.0. both axes. The major x-axis of the channel is the x-axis of the built up column.
Calculate the axial compressive stress in the column due to a concentric load of 815 kN
What is the critical slenderness ratio of the built up column?
