Transition zones such as level crossing and bridge approaches are critical links in railway networks due to higher degradation rates and maintenance needs. In this context, parametric optimization has been applied to improve the design in transition zones; however, it requires a more computationally efficient tool to support repetitive...

In transition zones, railway tracks experience significant inhomogeneity in their mechanical properties—more specifically in vertical stiffness. In such areas, conventional tracks (soft tracks) are typically encountered with other engineering structures with noticeably larger stiffness, such as bridges and culverts (stiff tracks). This...

The reason for this choice of topic is a life-long bewilderment towards the self-destructive potential of humankind. Supposed continuous accumulation of value is nurturing some of the most destructive and unvaluable events that this globe has ever seen. In many cases, the driver for what we do - our idea of what is valuable - seems to be leading...

Hyperloop is an emerging high-speed transportation system in which air resistance is minimised by having the vehicle travel inside a de-pressurised tube supported by columns. This design leads to a strong periodic variation of the stiffness (among other parameters) experienced by the vehicle. Also, along its route, the Hyperloop will encounter...

In this study, the flexural strength and fatigue properties of interfacial transition zone (ITZ) were experimentally investigated at the micrometre length scale. The hardened cement paste cantilevers (150 × 150 × 750 μm<sup>3</sup>) attached to a quartzite aggregate surface were prepared and tested under the monotonic and cyclic load using a...

This study investigates the effects of nanofillers on the interfacial transition zone (ITZ) between aggregate and cement paste by using nanoindentation and statistical nanoindentation techniques. Moreover, the underlying mechanisms are revealed through micromechanical modeling. The nanoindentation results indicate that incorporating...

Railway track transition zones are areas where there is a sudden change in the track-ground structure. They include changes between ballasted and slab track, bridge approaches, and tunnel entry/exits. They are often the location of rapid track deterioration, and therefore this paper investigates the use of auxiliary rails and soil improvement...

Many neighbourhoods that comprise the Western Garden Cities of Amsterdam are struggling with a low liveability. Their spacious layout however, offers great potential for densification within the city borders. My project, the Garden-Fresh City, shows an approach that both tackles issues with liveability and fulfills this densification potential...

Bolhuis, Remco (author)
An important subject in the research on the behaviour of railway structures is the validation of numerical models by means of in-track measurements. Many forms of track measurements have taken place all over the world, mainly in the sense of strain and acceleration measurements, but a more unexplored area is that of the direct measurement of...

This graduation arises from the urgent need to revitalize a problematic post-war neighbourhood in Amsterdam-West. There is a lack of places for residents to connect with each other and with their built environment. The zones between the private and public domain, the transition zones of the ‘General Expansion Plan’ aren’t enabling or encouraging...

Performance evaluation and maintenance planning are gaining importance with ageing rail infrastructure and increasing demand on track safety and continuous availability. The discrete/point railway assets (e.g. bridges, level crossings) together with extended track sections constitute the main railway network infrastructure. The former has...

El-Lithi, Mohamed (author)
Railways and other sources of environmentally induced vibrations often lead to annoyance and sometimes property damage. In this framework, transition zones are deemed as the most sensitive locations on the railway track, especially to high vibrations and impact loads. This causes high maintenance costs and is often very annoying, as the...

To probe into the mechanical behaviour of railway transition zone from the macro-meso aspects, a numerical model of transition zone is built that hybrids the Discrete Element Method (DEM) and Finite Difference Method (FDM). The DEM is utilised to simulate the ballast bed and sleeper, because it can consider the realistic ballast shapes and...

The port of Rotterdam was full and new mooring locations were required to host the largest ships in the world. And if there’s no space to expand on land, why not create land in the sea? That is exactly what The Netherlands did by creating Maasvlakte 2. The construction of Maasvlakte 2 started in 2008 and was officially completed on May 22nd ,...

Transition zones in railway tracks are locations with considerable changes in the vertical stiffness of the track support, which can be found near bridges, culverts and tunnels. In such locations, the stiffness variation and the differential settlement of tracks (uneven settlement of the track on the embankment and of the engineering structure)...

The steel–concrete interface (SCI) is known to influence corrosion of steel in concrete. However, due to the numerous factors affecting the SCI—including steel properties, concrete properties, execution, and exposure conditions—it remains unclear which factors have the most dominant impact on the susceptibility of reinforced concrete to...

Transition zones in railway tracks are the locations with considerable variation in the vertical stiffness of supporting structures. Typically, they are located near engineering structures, such as bridges, culverts, tunnels and level crossings.

Transition zones in railway tracks are locationswith considerable changes in the rail-supporting structure. Typically, they are located near engineering structures, such as bridges, culverts and tunnels. In such locations, severe differential settlements often occur due to the different material properties and structure behavior. Without...
