Which consequence results when undersized stirrups fail within concrete columns?

💡 Explanation

If stirrups are insufficient, shear stresses cause cracking; this degradation weakens the column's core due to reduced confinement. This, the mechanism of 'core spalling', creates longitudinal bar buckling, because the bars lack support, therefore choice A is correct, rather than increased performance.
