Evaluation of Equivalent SDOF Method for Nonlinear Dynamic Response Analysis of Railway or Highway Embankments
Publication: Lifelines 2022
ABSTRACT
A static push-over analysis method was employed to assess nonlinear behavior of embankments. Then, based on the results of the analysis, a simple method for carrying out dynamic nonlinear seismic response analysis of an embankment using an equivalent-single-degree-of-freedom (SDOF) model was proposed. It was confirmed that the sliding displacement of embankment calculated using the proposed method showed good agreement with that obtained using the finite element method. It consequently followed that the proposed method made it possible to carry out the dynamic responses of embankments in an economical manner compared to the conventional two-dimensional finite element method.
