摘要:
A resilient bridge structure, which not only ensures that the bridge can survive great earthquakes but also ensures that the bridge function can be restored without repair or with minimal repair, is one of the focuses of research on bridge earthquake engineering. The rocking structure, with its ability to control damage and self-center, is an effective way to achieve seismic resilience. In this study, a systematic review and summary of the history and development of rocking bridge structures is presented. First, the origin of the rocking structure and its application in bridge engineering are introduced. Then, research and development of the rocking bridge structure, the method of quasi-static behavior analysis, the dynamic analytical model, and the seismic design method are discussed. The literature review shows that the optimal structure and seismic performance of rocking bridges have been experimentally verified by researchers from various countries. Analytical theories and design methods have been continuously supplemented and developed. However, there are still some problems that need to be solved. The development of a rocking bridge needs to be oriented to the engineering needs, and aims to achieve a simple structure, reliable force transmission mechanism, and better durability. In the dynamic analytical method, the existing model does not consider the influence of the neutral axis depth, and it is necessary to develop a three-dimensional dynamic analytical model and a reliable coefficient of restitution to make the seismic response of the rocking bridge consistent with the real situation under earthquake conditions. Dynamic analysis of the full rocking bridge system should consider the constraints of boundary conditions. In seismic design, there are problems such as the determination of performance indicators, that is, how to balance the seismic performance and economic performance when determining the optimum performance of the rocking structure. © 2021, Editorial Department of China Journal of Highway and Transport.
