1. A built-up column has a length of 6 m. If consist of a core of W360 x 382 with two plates having
thickness of 10 mm welded as shown to form a box column. Assume Kx = 1.0 and Ky = 0.85 and A 36 steel
is used with Fy = 250 MPa
Properties of W 360 x 382
A = 48700 mm²
d=416 mm
br = 406mm
I, = 1410 x 10 mm
ly=536 x 10 mm²
