Milev, Vesko (author)Concrete and Steel are the materials with the largest market share in the construction industry and have been for a long time.<br/>With environmental awareness increasing, timber is regaining popularity due to the potential for carbon neutral and even carbon negative construction.<br/>Use of structural wood elements in bridges, however, is often...master thesis 2022

El Bamby, Hagar (author)Higher strength steels (HSS) hollow sections with steel grades from S460 up to and including S700 are becoming increasingly competitive in long span structures. Reduction of self weight is accomplished with the smaller wall thickness of the hollow section, leading to fabrication, transport and execution benefits. The use of HSS has a positive...master thesis 2021

Bogers, Lars (author)A steel frame is designed which is expandable and reducible at any time. In order to reduce the assembly and disassembly time of the frame a new type of beam-to-column connection is proposed, a so-called plug & play connection.The design codes cannot be used for the estimation of the structural performance of this connection. Therefor the...master thesis 2021

Ramkumar, Aravind (author)Injection Bolted Connections (IBC) are connections in which the cavity between the bolts and the plates (hole clearance) is filled with two-component epoxy resin. The oversized hole clearances allow for the reuse of all the structural elements in composite structures. Due to larger hole clearance, the possibility of slip occurrence in the...master thesis 2021

EL Kazaz, Akram (author)The orthotropic steel deck (OSD) is nowadays commonly used due to its advantages, such as its lightweight, short construction time, and high capacity to bear the loads. However, fatigue cracks occur in different welded connections in the OSD. In this study, the rib to-deck-plate connection at the crossbeam conjunction has been analysed. This...master thesis 2021

van Hulst, Jeffrey (author)One of the basic principles of the design of structures is that they must be sufficiently safe and meet the required reliability requirements. In Eurocode NEN-EN 1990 specific minimum reliability index values are defined, which depend on a certain reference period and reliability class. To ensure that the structures meet the reliability...master thesis 2021

Broeders, Koen (author)To optimize steel halls for this thesis, an optimization tool is created. This tool creates a parametric model and optimizes this model to its costs. The connections in the tool are limited to beam-column connections. <br/>The optimization starts with the input variables of the model, the most important input variable is the type of the beam...master thesis 2021

de Bruijn, Tom (author)Fatigue is one of the driving limit states in the design of wind turbines, as they are subject to varying loadsfrom winds, waves and gusts. One such governing area is the butt-welded connection from the shell to thering flange. To optimize the tower design and to help focus future research, more insight on the influence ofmaterial properties and...master thesis 2021

Boertje, Jean-Paul (author)A transition towards a circular economy is proposed by initiators like the Ellen MacArthur Foundation and architect Thomas Rau, in order to preserve and enhance natural capital, optimise resource yields, and minimise system risks. A circular economy seeks to ultimately decouple global economic development from the consumption of non-renewable...master thesis 2020

van der Ende, D.J. (author)An Orthotropic Steel Deck (OSD) is suspectable to fatigue and this forms an important design criterium. In this research the rib-to-crossbeam connection with a cope hole is studied using Finite Element Methods (FEM). The fatigue assessment is performed with the hot spot stress method making use of surface stress extrapolation. Two fatigue cracks...master thesis 2020

Pandit, Sayantan (author)The phenomenon of fatigue in orthotropic steel deck (OSD) bridges is a predominant problem because of complexity of the prediction methods. In the past, many researchers have studied the fatigue behaviour of various details in OSDs via both experiments and Finite Element Modelling (FEM). In the present research, the connection of open stiffener...master thesis 2020

Vidwans, Aditya (author)In steel structures, a lot of attention is paid to lightweight structure, i.e. reduction of dead load without compromising structural safety, integrity and performance as well as cost-effectiveness. Thanks to modern steel aluminium sandwich panel manufacturing technology a new possibility became available for lightweight structural design.The...master thesis 2019

Beld, Petra (author)Fatigue is an important issue for orthotropic steel deck (OSD) bridges and therefore a design criterium. Cracks will initiate at several locations of the bridge deck. It is likely that a crack at the trough web to deck plate joint at the crossbeam will initiate first. This crack initiates at the weld root and propagates through the deck plate. A...master thesis 2019

Misios, George (author)Wind turbines constitute a sustainable and effective solution to produce energy using wind power. Offshore wind turbines are becoming of special interest and more demanding with continuously increased diameters. However, their design poses great challenges, since the installation and fabrication tolerances in combination with high cyclic loading...master thesis 2019

Lopriore, Luca (author)The aim of this thesis is to present a design for a bicycle and pedestrian bridge which meets the requirements of Circular Economy; by incorporating strategies such as design for disassembly and modularity a structure is created which improves upon the long-term value of existing bridges. Circular Economy has in recent years begun to replace the...master thesis 2019

Rikeros Orozco, Daniel (author)There are several methods to perform fatigue assessment as described by the Eurocode 3 and the International Institute of Welding (IIW). The codes establish the relation between stress ranges and their respective number of cycles until failure of the detail. This method is called S-N curves, however this is based mainly on nominal stresses. A...master thesis 2019

Slingerland, Pieter (author)More offshore wind projects are being developed. Shallow locations are more occupied and a tendency to deeper water and to larger wind turbines is seen. These create more bending moment which can be more easily resisted by jacket substructures. The state of the art installation process of a jacket is as follows. The foundation piles are driven...master thesis 2019
