Effective Length Factor Example 03

In this example problem we'll explore the use of effective length factors in the calculation of the flexural buckling strength of a steel column in a moment resisting frame. "Determine the design capacity of column AB shown in the figure below. All steel is A992, all column bases are pinned, and the column is oriented such that it is bent about its strong axis as shown in the figure. The frame is unbraced in the plane shown - use alignment charts to determine K for strong-axis buckling. Assume that the frame is braced in the perpendicular direction – take K = 1.00 for weak-axis buckling. " ASCE 7 AISC 360-22 Compression American Institute of Steel Construction
