Which risk significantly increases when post-tensioned concrete beam tendons corrode within a bridge structure?

💡 Explanation

When tendons corrode, the tendon cross-section decreases and anchoring force is compromised because the reduced clamping force leads to increased stresses at the anchorage. Therefore, shear failures become more likely, rather than buckling, spalling, or chloride ingress, which depend on reinforcement and environment.
