Abstract
In this research, nonlinear dynamic analysis method using equivalent single degree of freedom model is proposed for seismic design of railway embankment. The response of embankment calculated by proposed method is well consistent with the response by 2D finite element method. From the results of static push-over analyses for various embankments, the model parameters used for the proposed method are characterized. These parameters can be represented by simple information such as the height of the embankment. Since proposed method can evaluate the dynamic response of railway embankments more convenient than conventional method, it is useful as the response evaluation method for a huge number of railway structures.
