Which risk is amplified when a crack develops perpendicular to prestressing tendons in a concrete beam?

💡 Explanation

When a perpendicular crack occurs, the exposed prestressing tendons experience accelerated electrochemical corrosion because the crack provides a direct path for chloride ions and moisture to penetrate the concrete. Therefore, corrosion rate increases, rather than shear failure, buckling, or creep, requiring different stress or loading states.
