Which mode increasingly threatens long, unsupported concrete columns under constant compression?

💡 Explanation

Euler buckling causes collapse because exceeding critical load induces lateral instability arising from geometric imperfections; therefore sudden bending occurs rather than plastic deformation, given the column's slenderness ratio exceeding limits without adequate lateral bracing against instability.
