A generation method for the rail random irregularity with arbitrary wavelength interval (WI) is developed, and its accuracy and efficiency are demonstrated. Then a moving wheel-rail-bridge interaction element is derived to establish the finite element equations of motion for the train-rail-bridge interaction system, and the flow chart of assembly and calculation for the system equations is give...

Track–bridge interaction (TBI) is an increasingly essential consideration for the design and operation of railway bridges, especially innovative bridge structure systems that constantly spring up over years. This paper focuses on characteristics additional forces in continuous welded rails (CWRs) 3 × 70 m integral rigid-frame Fuzhou–Xiamen High-Speed Railway, which a novel high-speed (HSR) syst...

Abstract In this study, the results of a vast experimental campaign on applicability smartphone-based technique for bridge monitoring are presented. Specifically, vehicle–bridge interaction (VBI)-based approach is exploited as cost-effective means to estimate natural frequencies bridges, with final aim possibly developing low-cost and diffused infrastructure system. The analysis performed using...

When vehicles interact with a bridge, vehicle–bridge interaction (VBI) system is created. The frequency and modal shape of VBI systems have been widely studied, but the damping has not adequately investigated. In recent years, several incidents abnormal bridge vibration due to changes in occurred aroused widespread concern society. Damping an important evaluation index structural dynamic perfor...
