Abstract
The Great Hanshin earthquake, on 17 January 1995, brought about serious damage to some underground reinforced concrete (RC) structures serving the subway in Kobe city, Japan. In this study, the seismic response of Daikai subway station during this earthquake is computed by FEM code WCOMD-SJ, which is a two-dimensional dynamic finite element program including path dependent RC smeared model, soil foundation model and interfacial model. The shear failure of intermediate column of the station can be reasonably simulated and it is concluded that the failure of the intermediate column is caused by low shear capacity and poor ductility. Enhancement of seismic resistance is also discussed using this FEM code.
