Table 1
Description of the damage scenarios according to the cutting sections shown in Figure
2.
| State | Damage | Percentage cutting (100% equals all tendons in the defined section cut) | | | 0.45 L | Over the pylon |
| #0 | Undamaged state | | | #1 | Cutting straight lined tendons in the lower part, at 0.45 L (20 tendons) | 33.7% | 0% | #2 | #1 + cutting 8 straight lined tendons in the upper part, over the pylon | 33.7% | 12.6% | #3 | #2 + cutting external tendons (56 wires) | 46.1% | 24.2% | #4 | #3 + cutting 16 straight lined tendons in the upper part and 8 parabolic tendons | 46.1% | 62.12% |
