What is buckling of columns?

Buckling of columns refers to the sudden failure of a structural member, typically a long, slender column, under axial compression. When the compressive load exceeds a certain critical value, the column deforms laterally, leading to a loss of load-carrying capacity. This phenomenon is influenced by factors such as the column's material properties, length, cross-sectional shape, and boundary conditions. Proper design and analysis are crucial to prevent buckling and ensure structural stability.
