Which catastrophic outcome results when inadequate lateral bracing prevents steel column flange movement?

A)Torsional buckling under critical load✓

B)Increased composite material shear stress

C)Elevated concrete compressive micro-cracking

D)Decreased beam bending moment capacity

💡 Explanation

Torsional buckling occurs because insufficient bracing allows the column flange to twist under load, activating the Saint-Venant torsion principle, therefore sudden catastrophic failure happens rather than more gradual yielding or member bending with excessive strains.
