Which outcome occurs when stress corrosion cracking develops within prestressing tendons of a concrete bridge?

💡 Explanation

When stress corrosion cracking develops, the synergistic effect of tensile stress and a corrosive environment causes intergranular crack propagation within the high-strength steel. This leads to brittle fracture because the material's ductility is reduced, resulting in sudden collapse rather than increased ductility, gradual yielding or chloride resistances which require different preventative mechanisms.
