Which risk is most elevated when post-tensioned concrete tendons experience corrosion induced volume expansion within a bridge structure?

💡 Explanation

When post-tensioned tendons corrode, the resulting expansive forces mechanically stress and damage the surrounding concrete, greatly increasing the risk of premature concrete fatigue failure. Therefore, accelerated fatigue results, rather than anchorage failure, enhanced reactivity or better response to seismic forces which depend on cohesion, aggregate properties and dynamic behavior respectively.
