buckling load
Isaac Kremer/ November 21, 2025/ / 0 comments
The axial load at which a column begins to deflect laterally and becomes unstable. Under a buckling load, a column cannot generate the internal forces necessary to restore its original linear condition. Any additional loading would cause the column to deflect further until collapse occurs in bending. Most columns in practice are subject to both compression and bending due to variation in material properties, initial crookedness in fabrication, or some eccentricity in load application. This bending often causes the actual buckling load to be slightly lower than the critical buckling load. (Ching, 1995)
