内容記述 | Railing on the bridges has safe functions to against vehicle collision loads. The impact angle is one of factors to affect impact index and design of railing grade. Impact angle mentioned in Japanese specifications is 15 degree. However, this study found that in some cases of curved bridges, its impact angles are larger than such mention. In addition, engineers suppose that in the same railing grade and truck conditions, curved railing is dangerous than straight railing. Therefore, this research is performed to study on performances of curved bridge railings subjected to larger impact angles, and verifies performances of curved railing. A full-scale test is an important methodology in the field. So, such test requires high cost and much effort. Therefore, the numerical analysis is main method of research based on the following procedures: (1) impact collision simulations are created by FE model using LS-DYNA 3D software; (2) to verify the performances of curved railing; and (3) to apply larger impact angles to curved railings. Numerical results are obtained, and give understand on performances of steel curved railings and proposal in design of curved railing on bridges. | |||||
