A W12x96 shape is used as a column member in a steel frame structure. The critical length for strong axis bending is Lcx=50 ft while the critical length for weak axis bending is Lcy=30 ft. Compute the “squashing” load for the column. Compute the slenderness ratio, Lcx/rx, for strong axis buckling. Compute the Euler buckling load, Pe, for strong axis buckling. Compute the slenderness ratio, Lcy/ry, for weak axis buckling. Compute the Euler buckling load, Pe, for weak axis buckling. Would this column be considered a “short” column? Explain your answer.
