1. A column 9 meters long is to carry a total service load (unfactored) of 890 kN. The member will be hinged at the top and bottom and will be braced about its minor axis at mid-height. Using A572 Gr. 50 steel., design the most economical section based on the following available section. Provide an explanation why your chosen section is the most economical. Neglect local buckling. Hint: Calculate all the capacity and compare the D/C ratio. W10x49 - Area = 9290 mm2,rx = 110.49 mm, ry = 64.52 mm W12 x 50 - Area = 9484 mm2,rx = 131.57 mm, ry = 49.78 mm W8 x 40 - Area = 7612 mm2,rx = 89.66 mm, ry = 51.82 mm W8 x 48 - Area = 9097 mm2,rx = 91.69 mm, ry = 52.83 mm

Question
1. A column 9 meters long is to carry a total service load (unfactored) of 890 kN. The member will be
hinged at the top and bottom and will be braced about its minor axis at mid-height. Using A572 Gr. 50
steel., design the most economical section based on the following available section. Provide an explanation
why your chosen section is the most economical. Neglect local buckling. Hint: Calculate all the
capacity and compare the D/C ratio.
W10x49 - Area = 9290 mm2,rx = 110.49 mm, ry = 64.52 mm
W12 x 50 - Area = 9484 mm2,rx = 131.57 mm, ry = 49.78 mm
W8 x 40 - Area = 7612 mm2,rx = 89.66 mm, ry = 51.82 mm
W8 x 48 - Area = 9097 mm2,rx = 91.69 mm, ry = 52.83 mm
