Identification of Vulnerable Zones on Steel Railway Bridges
… the static and dynamic analyses of steel railway bridges subjected to the action of moving trains on the Crocodile, Kalbaskraal, and Van Staden railway bridges located in the Western Cape. The parameters of the bridges were taken from the existing desktop information. Numerical simulations …

Análise da interação trilho-viaduto
… the interactions of forces between rails and railway bridge structure is presented. The forces are due to thermal variations and to forces caused by trains passing over the structure. The acting forces are distributed to the rails and structures by means of the ballast which is represented by …

Condition Monitoring of Structures by Using Ambient Dynamic Responses
… extent of small fatigue cracks in a simulated railway bridge.

A Sense of Time, A Sense of Self: The 'Lived Perspective' of the Walk
… may lead to the rerouting of the CSX Railway south of Washington, D.C., shutting down the existing line, I propose to convert the CSX Railway bridge that crosses the Anacostia River in Southeast Washington to an open public space. While other portions of the track may be demolished and …

Semplified seismic Vulnerability Assessment of Masonry Arch Bridges
… seismic vulnerability assessment of masonry arch bridges with common typologies in Europe. Bridges are, in most cases, the most vulnerable elements in the transportation network during an earthquake; therefore, their seismic vulnerability assessment is necessary for a proper planning of the …

Mitigation of differential movements at railroad bridge transition zones
… a rapid change in track structure, such as a bridge or crossing. These locations are prone to differential movement and require frequent resurfacing to maintain an acceptable track geometry for both passing freight and high-speed passenger trains. In an effort to reduce the frequency of track …

Vibration based assessment of Kalbaskraal rail bridge
… with vibration based assessment techniques for railway bridges. The methodology suggests a systematic visual assessment combined with the development of a finite element model which is calibrated by using modal parameters ascertained from vibration based testing. The bridge which was used as a …

Vibration of railway bridges in the audible frequency range
… level associated with a train travelling on a bridge is normally greater 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 …

Track-Bridge Interaction Effects in Heavy Haul Railway Viaducts
When continuously 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 …

A numerical investigation of the dynamic behaviour of continuous, multi-span railway bridges
The dynamic behaviour of railway bridges has been investigated for over a century [Ichikawa et al., 2000]. With the introduction of high speed trains in recent history, a host of complex problems regarding resonance have been observed and studied. These studies, which include Bjorklund [2004]; …

The calculation of noise from railway bridges and viaducts
… Limited are a designer and manufacturer of railway rail-fastening systems. As an organisation they have the capability to reduce the noise impact of bridges using resilient track components. They also have a commercial interest in providing such technology. Knowledge of the processes behind …

Reduction of water and bed levels in the lower Waikato River
… the formation of alternate bars at the Huntly Railway Bridge has been found to be exceeding 100 by an analysis of the gauging data at this site and at the Ngaruawahia Cableway. This critical width-depth ratio, 100, is much bigger than those suggested in the literature. The corresponding …

Seismic Resilience of Rail-Truck Intermodal Freight Transportation Networks
Railway and highway networks constitute the backbone of the US freight transportation network, and the rail-truck intermodal combination constitutes a popular emerging mode of freight transport. Although components of the intermodal network, namely railway bridges, highway bridges, roadways, …
