In case of a ship-to-bridge accident, the bridge structure may be required to bear huge lateral impact load, and the ship-to-bridge problem must be fully considered when designing the bridge passing through the water area. Otherwise, the bridge structure may be seriously damaged and even completely collapsed, which results in huge economic loss, casualties and negative social impact. Therefore, the anti-collision design of the bridge has become a major concern in bridge engineering.
