Description

The rigid frame viaduct is used for railway structures. But it is sometimes problematic on the train-running safety in the seismic conditions because of the differential displacement with adjacent structure by its low horizontal stiffness. The batter pile is one of the measures to gain the horizontal stiffness of the viaduct and expected to secure the train-running safety. But it has not been used recently for the railway and there are many unknown matters such as characteristics of lateral resistance in the case of earthquake. In this study we clarified the characteristics of lateral resistance of batter pile based on the static and dynamic non-liner analyses and experiments. And we studied its applicability for the railway structure. We studied the relatively acute-angled batter pile and found that it can control the horizontal displacement of structures and shorten the equivalent natural period even for the batter piles with the angle of approximately 5 degrees. Furthermore, it can also have not only seismic but also economical advantage in the case that train-running safety becomes the decisive factor of the structure’s specifications.
