| Abstract: | Taking a special-shaped landscape cable-stayed bridge with single slanted pylon as engineering background,a 3-D finite element model was established by the software ANSYS,and researching on the dynamic characteristics of the bridge,when there were no piles,piles in the bridge changed structure parameters of the bridge.There were little differences among the three situations.The first case was suggested to make the seismic response analysis.The results showed that the bridge has better seismic performance. |
