Determine the lightest, commonly used wide flange W250 section for the column shown below to support the factored axial load of Pf, = 2500 kN. Select a W250 section that is commonly used and is generally readily available. The column is 6m long. Consider pin support conditions at both ends of the column. As shown below, there are two lateral bracing members in the X direction, while no bracing exists in the Y direction. The steel is ASTM A992 steel and E = 200,000 MPa.

Question
Determine the lightest, commonly used wide flange W250 section for the column shown below to support the factored axial load of Pf, = 2500 kN.
Select a W250 section that is commonly used and is generally readily available. The column is 6m long. Consider pin support conditions at both ends of the column. As shown below, there are two lateral bracing members in the X direction, while no bracing exists in the Y direction. The steel is ASTM A992 steel and E = 200,000 MPa.
Take note:
(a) Your solution should include the iteration for selecting the lightest section.
(b) Using tables in the CISC handbook.
