Which structural failure occurs when pre-stressed concrete beam experiences chloride induced corrosion on steel tendons?

💡 Explanation

When chloride ions penetrate the concrete, it initiates corrosion of the high-strength steel tendons because it compromises the passive layer, leading to expansion and cracking in the concrete cover (spalling/delamination). Therefore, spalling and delamination results, rather than shear failure, buckling, or torsion which involve other independent mechanisms.
