摘要: |
Bridges must be designed to allow the free passage of vessels on active waterways, creating a risk of collision between a vessel and the bridge structure. In the case of a barge or flotilla of linked barges, a single collision can result in severe damage to the bridge, halting the passage of traffic on the water or land. To mitigate the damage caused by collisions, the American Association of State Highway and Transportation Official (AASHTO) provides engineers with detailed procedures for calculating vessel impact loads as part of a comprehensive risk assessment. Correct probabilities for the likelihood of how often a barge will go off course (the base aberrancy rate) are critical to these calculations. However, these probabilities are currently based on a limited number of data sets and assume technologies used in the maritime industry over 20 years ago. University of Florida researchers developed a revised barge impact probability expression applicable for the design of bridge structures located on Florida waterways |
