The pedestrian bridge of panelled chord truss objected in this study is under consider, and cost curtailment of the steel ball-joint is expected. The purpose of this study is to evaluate analytically dynamic performance and vibration serviceability of the timber truss pedestrian bridge with steel ball joint. The eigenvalue analysis was conducted by FEM based on three-dimensional analysis model, and then dynamic performance of this bridge was investigated. The three dimensional dynamic response analysis by walking of pedestrian was performed, and the vibration serviceability was investigated. After the vibration serviceability of this bridge had been grasped, the methods for vibration reduction such as boundary conditions at supported point and set of TMD were performed analytically, and the improvement of vibration serviceability of this bridge was investigated. |
