Influence of rotational speed on the response of rotation construction of a cable-stayed bridge
Abstract
In the swivel construction of large-tonnage cable-stayed bridges, the swivel speed often plays an important role in stability and safety. Based on the background of the largest swivel bridge across Xiangyang North Marshalling Station in Asia, this paper explores the influence of different rotational speeds on the response of swivel construction through model testing and finite-element analysis. The results of the model test and the finite-element analysis are compared and analysed. The results show that with the increase of the rotational speed, the fluctuation range of the vertical displacement and stress of the main beam of the bridge increases, indicating that the higher rotational speed will lead to a stronger dynamic response of the bridge structure.
