Unformatted text preview: cross-section is a channel with moment of inertia I, area A, and flange
width b. The ends are pinned at the point of load application. The distance between the centroid and the back
of the channel is e, and the compressive force F acts in the plane of the back of the channel and in the symmetry
plane of the channel. Figure 14.1 Slender Column Problem Sketch ANSYS Verification Manual . ANSYS Release 9.0 . 002114 . © SAS IP, Inc. 1–43 VM14

Only one-half of the structure is modeled because of symmetry. The boundary conditions for the equivalent half
model become fixed-free. Large deflection is needed since the stiffness of the structure and the loading change
significantly with deflection. The offset e is defined in the element coordinate system. Results Comparison
