| Abstract: |
A U-channel segmental concrete bridge has the advantages of reducing dead load and acting as a guard fence. It is necessary to analyze the behaviors of U-channel segmental concrete bridges and identify dynamic characteristics under vehicle-impact loading because they collapse when the edge beams have ruptured. In this study, static and dynamic vehicle-impact analyses were carried out for evaluating the safety of U-channel segmental concrete bridges under vehicle impact loading based on the AASHTO LRFD Specification (2007). Stresses and displacement from vehicle impact on a U-channel segmental bridge were analyzed. In addition, velocity and acceleration histories of vehicles were investigated. |
