| Abstract: | Dynamic behaviors of cable-stayed bridges with inclined or parallel cable planes are
carefully analyzed by taking Xupu Bridge in Shanghai as the prototype. This paper will mainly
discuss the effects of the bridge tower layout, such as both A-shaped or H-shaped towers and the
arrangement of subsidiary piers on dynamic characteristics of cable-stayed bridge and its flutter
instability. |

| Keywords: | Cable-stayed bridge Dynamic characteristic Flutter instability |
