Which bending failure occurs when compressive stress exceeds local strength in a steel I-beam?

A)Lateral-torsional buckling initiates
B)Web crippling deformations increase
C)Flange yielding plastically develops
D)Shear lag effects dominate

💡 Explanation

Lateral-torsional buckling happens when the compression flange deflects sideways; because the beam lacks sufficient bracing, this torsional instability occurs rather than pure bending. Thus, the compressive stress causes sideways buckling, therefore reducing the I-beam's overall load-bearing capacity.
