摘要: |
The objectives of this study were to develop safer bridge rail and transitional designs and to improve design guidelines. Ten bridge railings and two transitions were designed, tested, and evaluated in accordance with American Association of State Highway and Transportation Officials (AASHTO) requirements. The railings were designed using ultimate strength procedures and collision forces from earlier research. Design procedures, railing designs, and test results are presented. All designs demonstrated acceptable collision performance. |
