← TechnologyWhich risk increases when setting the tendon duct profile too high within a prestressed concrete bridge beam?
A)Increased shear cracking at supports
B)Reduced fatigue life of rebars
C)Premature concrete compressive failure✓
D)Elevated risk of tendon corrosion
💡 Explanation
Setting the duct profile too high results in excessive upward force from the prestressing, causing premature concrete compressive failure from exceeding stress limits. Therefore, compressive failure risk increases, rather than changing the fatigue life, corrosion or shear strength under normal loads because only the compressive strength changes.
