Abstract
The temperature deformation of Jiashao Bridge is a serious problem. In order to solve this problem effectively, a kind of rigid hinge structure is adopted in the middle of the bridge. Unit sparse plate bridge expansion joint for multi-direction-displacement is installed on the rigid hinge of this bridge. Vibration reduction tests are needed to verify the performance of the expansion joint and the service condition of the bridge structure. In this paper, a finite element analysis of the rigid hinge expansion joint is performed and a vibration reduction test platform is designed.
