Abstract

The railway bridge damping tenon device can not only provide lateral, longitudinal and vertical stiffness, which means that the displacement of main beam will be effectively limited under earthquakes. The energy dissipation system formed by shock-absorbing bearing-damping tenon also has significant energy consumption performance, which can meet the seismic demand of the bridge in the high seismic intensity zone of the southwest mountainous area. However, the gap and yield force of the damping tenon and the design parameters of shock-absorbing bearing have a significant impact on the seismic isolation effect and on the limitation of the main beam displacement. Therefore, this paper takes the typical high-speed railway bridge in the southwest mountainous near-fault zones as research object, and a refined finite element analysis model of the bridge system considering the nonlinear dynamic coupling effects such as geometry, material and contact is established to study the most suitable design parameters of damping tenon. In general, the shock absorption rate of the pier bottom bending moment increases with the increases of the tenon’s gap and decreases with the increase of the tenon’s yield force. However, the determination of the damping tenon’s design parameters requires a comprehensive consideration of displacement limitation of the main beam. The research results can provide a basis for the optimization design of railway bridge damping tenon device in the future.
