Strengthening of Steel Connections in a 92-Year-Old Railway Bridge Using Prestressed CFRP Rods: Multiaxial Fatigue Design Criterion

Alain Nussbaumer, Masoud Motavalli, Elyas Ghafoori, Hossein Heydarinouri

This paper presented a new retrofit system for strengthening the stringer-to-floor-beam double-angle connections in a 92-year-old riveted railway bridge in Switzerland, using prestressed carbon fiber-reinforced polymer (CFRP) rods. The strengthening system ...

Estimation of pedestrian origin-destination demand in train stations

Michel Bierlaire, Nicholas Alan Molyneaux, Flurin Silvan Hänseler

We present a framework for estimating pedestrian demand within a train station. It takes into account ridership data, and various direct and indirect indicators of demand. Such indicators may include link flow counts, density measurements, survey data, his ...

Analysis of Ballast Transport in the Event of Overflowing of the Drainage System on High Speed Lines

Giovanni De Cesare, Tamara Ghilardi, Mona Jafarnejad Chaghooshi, Elena Battisacco

The transport of ballast caused by the overflowing of longitudinal drains is a prime example of the interactions between the railway track and its environment. In such conditions, water flowing from the platform, along with debris, may drag the ballast off ...

The effect of magnetic islands on ITG turbulence driven transport

In this work, we address the question of the influence of magnetic islands on the perpendicular transport due to steady-state ITG turbulence on the energy transport time scale. We demonstrate that turbulence can cross the separatrix and enhance the perpend ...

Modelling degradation processes of switches & crossings for maintenance & renewal planning on the Swiss railway network

Willem-Jan Zwanenburg

Approximately 25 percent of the budget for the maintenance and renewal of railway tracks –in Switzerland more than a billion Swiss Francs– is used for the switches (points) and crossings (S&C). While in the mean time the budget expenditure for the maintena ...
