Investigation into the structural interaction between piles and caps in bridge engineering

Abstract

With the continuous advancement of construction technology, the pile-plate structural system, originally developed for railway engineering, has increasingly found applications in highway engineering. In this study, we propose a novel design for the pile-plate connection nodes. The innovation lies in the integration of energy-dissipating elements at these nodes, which enhance the structure’s ability to absorb and mitigate dynamic loads. Additionally, the use of non-shrinkage concrete at the joints ensures improved durability and long-term stability, addressing common issues associated with conventional concrete connections. Together, these enhancements demonstrate a significant improvement in both the structural performance and resilience of pile-plate systems in modern highway applications.
