| Abstract: |
| As a new super\|long\|span cable\|supported bridge type, the cable\|stayed\|suspension bridges synthesize the characteristics of cable\|stayed bridges and suspension bridges. On the base of spatial finite element modal, the modal analyses results of the Lindin East Sea\|route cable\|stayed suspension bridge design project is obtained. The inherent vibration characteristics of cable\|stayed\|suspension cooperation system and the influence of longitudinal restraint conditions in main girder and assistant pier setting. The results can provide theoretic reference for the dynamic analyses of the cable\|stayed\|suspension cooperation system. |
