Which risk increases when a pre-stressed concrete column's tendon spacing exceeds design specifications?

💡 Explanation

Increased tendon spacing reduces confinement, therefore increasing the unsupported length of the concrete, leading to potential buckling. This buckling is specifically due to reduced 'lateral support', rather than reduced chloride resistance, creep, or shear strength that occur due to concrete composition.
