Numerical analysis on longitudinal seismic responses of high-speed railway bridges isolated by friction pendulum bearings [PDF]

, 2018
As to analyze the effects of friction pendulum bearings (FPB) on the responses of simply supported bridges on a high-speed railway under longitudinal earthquakes, a spatially integrated track-bridge model with a CRTS II slab ballastless track and FPB was

Benefit of damping in structural concrete for railway structures and track components [PDF]

, 2019
There are two types of modern railway tracks including ballasted and ballastless tracks. Ballasted tracks are optimally designed for suitability to railway operations with train speed less than 250 km/h, while ballastless tracks are more suitable for ...

The Wavelength Characteristics of Vertical Deformation and a Train Dynamics Simulation of Long-Span, Cable-Stayed Bridges Under Complex Loads

Applied Sciences
Ballastless tracks have a high smoothness, but the corresponding laying requirements are strict. Therefore, the maximum span of cable-stayed bridges that can accommodate ballastless tracks is 392 m.

Study on the dynamic contact relationship between layers under temperature gradients in CRTSⅢ ballastless track

High-Speed Railway
In areas with large temperature differences, the uneven distribution of temperatures in the CRTS III ballastless track slab due to daytime sunlight can cause warpage deformation, leading to periodic rail irregularities that increase the wheel-rail impact
