Exploration of a Reverse Turbo-Brayton Cryocooler for Carbon Neutral Aeronautical Applications: Integrated Cryocooler Design and Tank Modeling for Cryogenic Liquid Hydrogen in Long Range Flight

Climate change is a pressing issue. Hydrogen aircraft are an excellent alternative to current kerosene aircraft, and appear to be the most viable long-term solution for net-zero flight. One of the main challenges for hydrogen aircraft is to sustain a low boil-off rate. This research explores the solution of active cooling of the LH2 mixture in...

Parametric study regarding the influence of preliminary design parameters of a long-span timber footbridge on the human-induced dynamic behaviour

Dynamic behaviour often is a topic of concern in the design of pedestrian bridges. It is time-consuming to assess and little is known about the way it is influenced by the characteristics of a bridge. In many cases, a bridge needs testing after is has been finished to determine the specifications of a damper. <br/><br/>Striving to reduce the...

Towards a Sustainable Bridge Design: With the support of optimisation processes and decision making systems

This research aimed to design a new bridge for the city of Rome, Italy, through the support of modern optimisation and decision-making processes that can be implemented to make informed choices regarding aesthetic performance, structural firmness, and environmental impact. The bridge’s design was carried forward considering the city’s plans for...

Improving applicability of a parametric model for breakwater layout design

During a previous research project, a parametric model for conceptual layout design has been developed. The model uses optimisation using genetic algorithms to approach the optimal breakwater layout for specific locations. <br/>The developed model serves as a successful proof-of-concept. In the model, several aspects of design have been...

Optimisation of Complex Geometry High-Rise Buildings based on Wind Load Analysis

Wind analysis for the structure of buildings is a challenging process. The increasing strength and frequency of wind events due to climate change only add higher demands. In addition, high-rise buildings are growing in number and include many of unconventional shape. Current methods used in practice for calculating structural wind response...

Optimisation of complex geometry buildings based on wind load analysis

One result of climate change is the increasing strength and frequency of wind events. This creates a problem for the also increasing number of high-rise buildings many of which are of unconventional shape. However, current methods for calculating wind response either do not account for these geometries, such as the Eurocode or are prohibitively...

The implementation of alkali-activated concrete in jointless ground floors

To realise more sustainable industrial ground floors the implementation of alkali-activated concrete is considered for jointless elastically supported ground floors. Such floors are realised with large areas without dilations, the shrinkage reduction is therefore restrained causing cracks to arise at the top surface of the floor. The control of...

The modular post-earthquake shell: A multi-objective parametric structural design approach

In April 2018, a graduation project in the field of architecture was concluded. The project entailed the design of a temporary community centre in the earthquake-damaged historic town centre of L’Aquila, Italy. The underlying social concept was focused on participation of the local population in the construction of the community centre. The...

Green-linking Rotterdam Zuid

This research is aimed at the necessity and the design of a new city bridge in the city of Rotterdam, the Netherlands, and how green could be implemented in such a structure. Through analysis of issues regarding the connection of Rotterdam Zuid over the Nieuwe Maas, the city’s plans and ambitions, precedent bridge designs and different...

Breaking Barriers: A parametrically optimised bridge design crossing the Nieuwe Maas

This research is aimed at the necessity and the design of a new city bridge in the city of Rotterdam, the Netherlands, and how this design could be parametrically optimised using the modern digital tools that are available. Through analysis of the issues regarding the connection of Rotterdam South over the Nieuwe Maas, the city’s plans and...
