| Abstract: | The analogy criterion of model testing of ship collision with bridges is proposed by the theorem of Buckingham in this paper. Based on a practical bridge across the Quanzhou,the scaled model testing on the forces of ship collisions was conducted.The testing result was compared with various code expressions. It's shown that the design force of ship collision specified by AASHTO specifications is in good accordance with the testing result. However, the design force of ship collision specified by current design specifications of highway bridge of China is obviously lower than the testing result. |
