内容記述 | The Japanese design specifications of guard fences were revised in 2004. Since this revision, when guard fences are produced, it has been regulated to improve the choking rate from vehicles, and also to satisfy the requirements of the design specifications, the development of new bridge railing guard fences has been done in Japan. In this study, firstly, the impact performance of the fence posts of new bridge railing guard fences was verified in the heavy steel ball collision experiment. Secondly, the Finite Element models of the fence posts of new types for numerical analysis were developed. The analytical results were compared with the experimental results, and the FE models were proved to be valid and practical. Thirdly, the impact performance of the fence posts of new types was quantitatively verified by comparing the difference between the fence posts of new types and the fence posts of existing type. As a result, it was verified that the fence posts of new types had better performances at shock-absorbing properties than the fence posts of existing types. In addition, it was verified whether the impact performance of the fence posts of new types was equally demonstrated as guard fences in the full-scale truck collision analysis. | |||||
