Abstract: The damages to Dakai subway station in 1995 Hyogoken-nanbu earthquake are analyzed in detail. The earthquake response of Dakai subway station is modeled by the 2-D substructuring methods (program SASSI2000, developed by John Lysmer et al.) with ground motions inputted in different directions. In this method, the dynamic soil-structure interaction is considered; and the effect of soil nonlinear dynamic property is considered by equivalent linearization model (program SHAKE91, developed by Schnabel et al.). The soils above the subway are considered as an affiliated structure of subway. The results prove that the model used is validation and the collapse of the columns in Dakai station was induced by both of the horizontal and vertical vibrations. The dynamic response of Dakai subway station calculated in this paper accorded well to all kinds of damages caused by the 1995 Hyogoken-nanbu earthquake.

Key words: subway station, substructuring subtraction methods, aseismic design, earthquake response
