Question
A built-up section consisting of W 350 x 90 with two 12-mm plates welded to form a box section as shown in the figure. The section is used as a column 10 meters long.
Properties of W350x90:
b_f = 250 mm
t_f = 16.40 mm
d = 250 mm t_w
= 9.50 mm
I_x = 266 x 10^6 mm^4
I_y = 44.54 x 10^6 mm^4
A = 11,550 mm^2
Determine the following:
a. Moment of Inertia along X and Y axes. *
b. Polar Moment of Inertia with respect to X and Y axes.
c. Section Modulus, Sx and Sy
d. Radius of Gyration, rx and ry
