← TechnologyWhich outcome occurs when a steel I-beam buckles under excessive axial compression?
A)Sudden and catastrophic structural failure✓
B)Gradual stress-strain curve linearization
C)Increased beam tensile stress resistance
D)Uniform compressive yielding observed
💡 Explanation
Buckling leads to catastrophic failure because crippling due to the Euler buckling mechanism occurs rapidly under pressure, therefore causing sudden collapse, rather than gradual yielding that might be anticipated under simpler compressive loads.
