Abstract
In this paper, comparison between FEM seismic deformation analysis and two-dimensional FEM dynamic response analysis was performed, for a typical underground railway two-layered structure with two spans which was assumed to be composed by linear elastic elements. This study was performed under the assumption that the earthquake was rated at the level 2. As the results, the applicability of the seismic deformation methods using static FEM technique to a typical underground railway two-layered structure with two spans was confirmed. Taking non-linearity of structural beam into consideration, damage simulation due to FEM seismic deformation method was carried out, for the Daikai Station of Kobe Rapid Transit System which was severely damaged by the 1995 Kobe Earthquake, followed by confirming the effectiveness of FEM seismic deformation method.
