This work studies vibration and radiated noise from railway systems using the 2.5D Boundary Element Method (BEM) formulation in the Bézier-Bernstein space. The proposed method allows the representation of the exact geometry of the track as it is done in computer-aided design (CAD) models. Thus, it ...

Abstract. Train-induced vibration is a growing concern in China for tracks in close proximity to buildings, in particular, for over track building in metro depots. Over-track buildings generally include heavy transfer structures due to irregular spacings between ground columns in between the tracks....

In the field of railway ground-borne noise and vibration, emission levels are strongly dependent on the track and ground properties so that measurements at different sites cannot be directly compared. Therefore, to compare the ground-borne noise and vibration performance of different vehicles, it is...

Railway ground-borne vibration emission is an ongoing issue, which shows a need for vibration emission characterization and prediction where the approach used should ensure transferability from one site to another. This transfer is often calculated using heavy frequency-based (narrow band) numerical...

In this paper, a meshless method for the simulation of dynamic soil-structure interaction prob-lems is verified in a three-dimensional context. The proposed meshless method considers a set of collocation points at the ground surface portions where the structure’s foundations will be located, whils...

The demand for train speed is getting higher and higher. When the train increases to the critical speed, it will cause resonance of track and substructure, which will adversely affect the train driving safety. At present, ballastless track is widely used in high-speed railway, and the vibration char...

Technological advances in recent years have allowed the emergence of high-speed train (HST) transport. However, high speeds have the potential to cause excessive ground vibrations that can affect the track structure and the surrounding area. This can potentially cause passenger discomfort and in the...

Base isolation is an established method of limiting the transmission of traffic-induced vibration into buildings. Despite this, the available design guidance is limited, and significant questions remain concerning how the vibration isolation performance may be optimised for a particular building. Re...

Among modes of transportation, railway transport has received increasing attention lately especially due to its capability of running fully on electricity, which can be generated from green sources. With the increasing demand on railway transportation, the previously acceptable issues caused by rail...

Vibration induced by the train passing causes the stress fluctuation of structural element, which makes it essential to investigate the train-induced fatigue damage of the railway bridge structure. This paper proposes a method for fatigue damage assessment of the rail-way steel truss bridge based on...

Controlling the train-induced vibrations of environmental infrastructures, especially the buildings along the high-speed railway, has become an essential demand and hard challenge. In attempts to accurately predict the dynamic responses of ground and buildings adjacent to the railway, based on an ex...

The limit values commonly used in Sweden and Norway for structure borne noise from railroad are strict when seen in an international context. At the same time, tunnels with low coverage are regularly built through densely populated areas, which can cause complaints about high structural borne noise ...
