Track-Bridge Interaction Effects in Heavy Haul Railway Viaducts
… welded rails are placed over a bridge, the track and the bridge interact via the ballast in the case of ballasted track or track slab in the case of non-ballasted track. This interaction, commonly referred to as track-bridge interaction results in force transfer between the track and the …

Shared memory parallelization for large scale 3D polyhedral particle simulations
… particle granular flow simulation, full-scale ballasted track simulations, and parametric study of angle of repose: The code successfully captured the runout distances of dry granular flow. This novel approach extended the capability of simulation size up to 52 million 3D polyhedral …

Vibration of railway bridges in the audible frequency range
… than that for a train travelling on plain track. It is sometimes the bridge noise that causes the highest levels of disturbance to people in the vicinity or triggers action under<br/>regulations such as the Environmental Noise Directive. Consequently, there is a need to study means of …

Modelling Transition Zones and Optimal Design Adjoining Tunnels and Bridges
Track transitions, such as bridge approaches, road crossings, and shifts from slab track to ballasted track, are known to be locations where track degradation accelerates due to dynamic and high impact forces. As a result, there is a higher differential settlement, which can cause an abrupt change …

Longitudinal forces in continuously welded rails due to nonlinear track-bridge interaction for loading sequences
… stiffness in longitudinal direction between the track and bridge. This additional load occurs as a consequence of the employment of a nonlinear stiffness law which increases the restoring force by a factor of 3 when the situation of the track changes from ‘unloaded’ to ‘loaded’ due to a passing …
