The result shows that the seismic behaviors of these bridges are different largely even under the same earthquake. These behaviors include the displacement and force response of the main components in three cable-strayed bridges which are compared in detail as follows. Based on damage analysis of the towers, failure modes of the three different systems were concluded. For RS, the bottom of the middle tower is a vulnerable region, this means the failure is focused here and plastic hinge formed under earthquake. The FS is damaged most severely, in which the edge tower has a largest damage index. While the seismic responses of PEDS are decreased largely compared to FS due to the employ of viscous dampers and the damage indices for all towers are cut down, remarkably the dissimilarity of damage condition between middle tower and edge tower can be adjusted by changing the damping coefficient of the viscous material, the damage of middle tower can be identical to that of edge tower if the damping coefficient is rational.
