Dynamic Characteristics of Pylon of Cable-Stayed Bridge with Inclined and Arched Tower during Construction

Abstract:

The structure of cable-stayed bridge with inclined and arched tower is complex and the force is complicated, especially the pylon, whose design and construction require detailed calculation and analysis. In case of the construction of Datong Nansanhuan Yuhe bridge project, in order to ensure the safety during its construction, the detailed construction plan was planned and the finite element model was established to analyse the dynamic performance of structure during construction of pylon. The result shows that, during the construction of low pylon, each frequency order of bridge structure is reduced to a steady level with the pylon completed gradually, and the low frequency changes moderately.
