How Bridge Engineers Design Against Ship Collisions
Practical Engineering・2 minutes read
A container ship collision caused the Key Bridge collapse in Baltimore, resulting in casualties and infrastructure damage. The incident underscores the importance of designing bridges to withstand vessel impacts and the complexities involved in ensuring bridge safety standards.
Insights
- Collisions between ships and bridges, known as "allisions," have been a persistent issue, leading to significant bridge collapses over the years, prompting updated bridge codes to consider vessel impacts in design and emphasizing the importance of structural engineering to prevent such disasters.
- Engineers aim to minimize the probability of bridge collapse from ship impacts by adjusting factors like pier distance, utilizing protection systems, and employing complex calculations to estimate impact forces, showcasing the intricate considerations involved in designing bridges that can withstand potential vessel collisions.
