WebStability and Buckling Readings: BC Ch 14 Learning Objectives Understand the basic concept of structural instability and bifurcation of equilibrium. Derive the basic buckling … The ratio of the effective length of a column to the least radius of gyration of its cross section is called the slenderness ratio (sometimes expressed with the Greek letter lambda, λ). This ratio affords a means of classifying columns and their failure mode. The slenderness ratio is important for design considerations. All the following are approximate values used for convenience.
