s shown in the sketch, an interior column AB in a steel frame carries a factored axial compressive load, Pu = 1540 kips. The column is braced at the top and bottom and the mid- height in the perpendicular plane, and sidesway in the plane of the steel frame is allowed. The columns are 12-ft long, and the columns above and below the column AB are the same size as AB. The adjacent girders are W 18×50 and are 32-ft long. Use A992 steel with Fy = 50 ksi, select the lightest W-section for the column AB. Use stiffness reduction factor where applicable.

s shown in the sketch, an interior column AB in a steel frame carries a factored axial
compressive load, Pu = 1540 kips. The column is braced at the top and bottom and the mid-
height in the perpendicular plane, and sidesway in the plane of the steel frame is allowed. The
columns are 12-ft long, and the columns above and below the column AB are the same size as
AB. The adjacent girders are W 18×50 and are 32-ft long. Use A992 steel with Fy = 50 ksi,
select the lightest W-section for the column AB. Use stiffness reduction factor where applicable.
