How do you design slender members to AISC ASD 89?

To design slender members according to AISC ASD 89, first determine the effective length and slenderness ratio of the member. Check the applicable design criteria for buckling and strength, including the use of the appropriate design equations from the AISC Manual. Ensure that the member meets the criteria for both flexural and lateral-torsional buckling, and verify that the design loads do not exceed the allowable stress for the material used. Finally, confirm that the overall stability and serviceability requirements are satisfied.
