In this paper, a simply-supported bridge and a multi-frame bridge model are established. According to the variations of the type,stiffness,location of restrainers and earthquake-input etc, the digital simulated studies are done and the results show that the ratio of stiffness between restrainers and pier(frame), ranging from 0.5 to 2, is better. The research on applications of the current design method for the two examples of structures is presented.
