Seismic performance objectives were studied to quantify structural performance level corresponding to the fortification. The potential plastic hinge regions in the piers were identified by nonlinear time history analysis to discover the collapse status under intense earthquake. To figure out the seismic limit state of this bridge under different levels of earthquakes, applicability of the design parameters and structural behaviors were investigated comparatively. Seismic ductility and isolation design were studied respectively to balance the dilemma between driving comfort and seismic safety. The numerical results of the fragile sections suggest that this kind of bridge is much applicable on the railway across earthquake-prone area.
