Radius of gyration 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. Web• The slenderness ratio L/r, where r is the smallest radius of gyration of x-section. Buckling will occur about the axis where this ratio gives the greatest value.

WebDec 21, 2024 · r – Radius of gyration; K – Effective length factor; and L – Length of the column. For example, a column of Leff = 8.0 m and r = 28.87 mm: λ = 8.0 m / 28.87 mm = 277.1 The effective length Leff represents the longitude between the inflection points in the buckled column. The slenderness ratio comes from Euler's equation for columns: WebThe radius of gyration can be thought of as the radial distance to a thin strip which has the same area and the same moment of inertia around a specific axis as the original shape. Compared to the moment of inertia, the radius of gyration is easier to visualize since it’s a distance, rather than a distance to the fourth power. 🔗
