2015-2-20 · The term "L/r" is known as the slenderness ratio. • A higher slenderness ratio means a lower critical stress that will cause buckling. • Conversely, a lower slenderness ratio results in a higher critical stress (but still within the elastic range of the material). Column sections with large r-values are more resistant to buckling.
