Dynamic analyses are carried out for Meiko Central bridge, a long-span cable-stayed bridge, by using the assumed ground motions. Both material and geometrical nonlinearity are taken into consideration. Due modeling is used for the important members that yield in the seismic analyses. The nonlinear seismic behaviors and members’ damage sequence of the cable-stayed bridge are investigated by analyses until ultimate state. It is verified that response value of Meiko Central bridge is small and safe when subjected to Tonankai earthquake, which have longer period.
