the vibration of cable-stayed bridges subjected to the passage of high-speed trains is studied in this article. the moving train includes a number of wagons, each of which is modeled as a four-axle system possessing 48 degrees of freedom. the car model is nonlinear and three-dimensional and includes nonlinear springs and dampers of primary and secondary suspensions, dry friction between differe...

A bridge is an essential component of transportation networks and plays a crucial role in the operation infrastructure, so maintaining this structure to guarantee regular bridges healthy condition needed. The establishment model numerically critical step evaluation because many cases test can be done numerically. generated results then verified adjusted with real or full-scale test. This resear...
