Question

A column section is fabricated by welding a 12 mm x 150 mm cover plate to the top of a W 18 x 65. Assume that the components are connected in such a way that the member is fully effective. Length of column is 6.0 m.

Properties of W 18 x 65

A = 13323 mm2

d = 466.09 mm

Ix = 445 x 106 mm4

Iy = 23 x 106 mm4
rx = 190.25 mm

ry = 24.93 mm

Fy = 345 MPa

bf = 192,79 mm

tf = 19.05 mm

tw = 11.43 mm

Zx = 2179 x 103 mm3

a. Determine the critical slenderness ratio of the built-up column section. 

b. Determine the design and allowable strength of the built up section based In flexural buckling. (kN)
