Which risk increases when a post-tensioned concrete beam experiences anchor corrosion in a marine environment?

💡 Explanation

When anchors corrode in a marine environment, the prestressing force decreases because the steel cross-section is reduced, leading to a lower compressive force on the concrete, which could cause buckling. Therefore, buckling risk increases, rather than shear failure, bridging, or increased resistivity which require different material behaviour changes.
