The Effective Length of Columns in Unbraced Frames

The AISC Specification requires the determination of if-factors for columns in unbraced frames by some rational analysis, that is, a stability analysis. The elastic ... Kl/r, as shown in Fig. 3. Because of residual stresses and initial out-of-straightness, inelastic action is assumed to begin at an average stress level of 0.5Fy. The value
