| Abstract: | Based on finite element method and considering the two structure designs with or without subsidiary piers,this paper takes the south Taihu Bridge for example calculates and analyses the dynamic performance of the single tower and double-cable-plane prestressed concrete cable-stayed bridge by establishing a space power computation module,so as to promote the study of the dynamic performance of prestressed concrete cable-stayed bridge. |

| Keywords: | cable-stayed bridge finite element dynamic performance self-excited vibrational frequency subsidiary pier |
