Hylkema, Fokke (author)Gates are an essential part of navigational locks, as they are responsible for creating a water barrier and can be repositioned to allow passage for maritime transit. Most lock gates are made of steel but a recent project in Sweden challenged the status quo by constructing the first stainless steel lock gate. The main question of this thesis...master thesis 2023

Idsinga, Johannes (author)An extensive Life Cycle Analysis (LCA) is used to determine the efficiency in reducing the carbon footprint of a graving dock. Firstly by identifying the hotspots in a base design, and then by comparing the various design alternatives. The focus is on reducing the amount of reinforced concrete used in the design of the dock floor by adding...master thesis 2023

Stellinga, Coen (author)To reduce the environmental impact or cost of a civil engineering structure their designs are optimized. A promising method to optimize are iterative optimization algorithms. If both the design calculations and the iterative optimization algorithm are automated, an optimized design solution can be found within a feasible timeframe. To be able to...master thesis 2023

Jiang, Quanxin (author)The need for more accurate cleavage modelling is particularly acute for a new generation of high-strength steels because they obtain their favourable properties through complex, multi-phase microstructures. One of the challenges in cleavage modelling is the strong sensitivity to material characteristics at the microlevel. This thesis proposes a...doctoral thesis 2023

Morete Barbosa Bertolo, V. (author)The use of materials in increasingly severe service conditions raises concerns about structural safety with respect to cleavage fracture. There are three main material-related challenges that structures face under harsh environments: 1) the trade-off between strength and toughness; 2) the ductile-to-brittle transition behaviour of BCC high...doctoral thesis 2023

Kallan, Daniel (author)The use of precast Reinforced Concrete has been the norm for the construction of tunnel linings for decades. However, the use of Steel Fiber Reinforced Concrete is gaining popularity due to its beneficial mechanical properties, improved sustainability, improved durability, and lowered costs compared to traditional Reinforced Concrete (RC). The...master thesis 2023

Atreya, V. (author)Dual-phase (DP) steels are an important class of advanced high-strength steels (AHSS) and constitute a major share of steels for the automotive industry. A microstructure consisting of hard martensite embedded in a soft ferritic matrix gives them a good combination of strength and ductility. The martensite formation in the microstructure from...doctoral thesis 2023

van Leeuwen, Lucia (author)The world is facing environmental change, mainly due to human actions. To prevent serious environmental, economic, and societal impacts of climate change, all United Nations Framework Convention on Climate Change (UNFCCC) member countries have committed to limit global temperature increase to 2 degrees Celsius above pre-industrial level by 2050....master thesis 2023

Yan, R. (author)High-strength steel (HSS) has higher strength but lower ductility than mild steel. The cross-section of the structural members may be reduced using HSS instead of mild steel, provided the buckling of elements does not govern the failure. The reduced member size benefits the environment and economy by means of less energy consumption, less carbon...doctoral thesis 2023

DASOPOULOS, DIONYSIOS (author)Thick-section high strength steels (HSS) are widely used in engineering applications with requirements of high toughness and strength. Structural components are commonly joined by welding, known to significantly degrade the mechanical properties of steel due to changes in microstructure (e.g., grain size coarsening and martensite-austenite (M-A)...master thesis 2023

Ruminy, Justine (author)The climate emergency calls for a global shift towards a low-carbon economy, to preserve natural resources and biodiversity, while limiting global warming and its consequences. This project focuses on the impact of distribution centres, intended for the storage of commercial goods. Warehouses are characterised by large flexible spaces and simple...master thesis 2023

van de Leur, Sophie (author)Timber high-rise buildings have been gaining in popularity. However, due to the low material stiffness of timber the stability systems of these buildings are often made with steel or concrete. To avoid this the material efficiency of the timber stability systems must be improved. The most material efficient stability systems for timber high-rise...master thesis 2023

Schmitter, Sacha (author)The Iron and Steel (I&S) industry is the largest contributor to man-made greenhouse gas emissions. The products of the I&S industry are a constant necessity, e.g. for civil infrastructure. In addition, their processes are interwoven with coal and natural gas properties, which classifies this industry as a ’hard-to-abate’ sector....master thesis 2023

Yan, R. (author), Mela, Kristo (author), El Bamby, H. (author), Veljkovic, M. (author)The newest version of prEN 1993-1-8 (2022) prescribes a material factor (Cf) to reduce the design resistance of welded joints made of high strength steel (HSS) mostly due to the lack of available experiments, given the less ductility of HSS compared to mild steel. Additionally, it is stated that the material design yield strength should not...journal article 2023
