2. Two channels are welded at the top and bottom flange to form a box column and a compact section Properties of each channel A = 5350 mm² d = 250 mm b, = 100 mm t₁ = 15 mm t₂ = 10 mm I, = 52 x 10 mm 1,= 5 x 10 mm = 29 mm F₁==345 MPa If the length of the columns 4 m and K = 1.0 both axes A. Determine the critical slenderness ratio of the built up column B. Calculate the allowable and ultimate axial load of the column
