Objective
To verify the steel W-shape column design in combined axial and flexure
Problem Description [Ref .1, Example H.4]
Select an ASTM A992 W-shape with a 10-in nominal depth to carry the following load effects:
Pu = 30 kips, Mux = 90 kip-ft, Muy = 12 kip-ft.
The unbraced length is 14 ft and the ends are pinned. Cb = 1.14. The member is non-sway.
Finite Element Model
1 beam elements with appropriate material and design criteria assigned
Model type: 3D Frame
Results
The following table shows some intermediate and final results during the design. The program gives comparable results with the reference [Ref 1].
