| Abstract: | Relevant factors affecting the impact coefficients of the bridge are analyzed in the paper, with the dynamic response characteristics of a certain FRP light bridge with vehicles passing it at different speeds studied by means of dynamic loading tests and dynamic analyses. According to the results of the dynamic loading tests and the dynamic analyses, reference values of impact coefficients of the FRP light bridge are presented in the paper, which may serve as a useful reference for the design of FRP bridges. |
