Cijsouw, Willem (author)For the E39 highway in Norway a project is underway to replace the ferry crossing in the Sognefjord with a fixed crossing. Previous thesis projects have resulted in a design for a 4500 m long buoyancy bridge which consists of 22 concrete pontoons that carry a steel truss superstructure. To reduce lateral movements the pontoons are fixed to a...master thesis 2018

Creusen, Koen (author)The offshore wind industry is developing larger turbines, often placed in deeper water. This requires larger foundations. The predominant foundation type is the steel monopile, typically consisting of two large diameter pipes, the monopile (MP) and the transition piece (TP). The Wedge Connection is a new type of connection between these...master thesis 2017

Chondrogiannis, K. (author)The aim of this thesis is to investigate the feasibility of determining the preload in bolts in High Strength Friction Grip Conections and performing in situ measurements. The magnitude of the preload is important for the behavior of High Strength Friction Grip Connections, as it defines the fatigue life of the connection and limits the...master thesis 2017

Nijgh, Martin (author)The purpose of this thesis is to investigate the short- and long-term behaviour of injected bolted connections (IBCs) with oversize holes for various injection materials. A central theme in this thesis the demountability of IBCs, as a result of which several release agents are tested for their suitability in and effects on IBCs. <br/>Injection...master thesis 2017

De Ruiter, T.M.H. (author)Research shows that the fatigue strength of a Very High Strength Steel (VHSS) can be significantly negatively effected by welds in a structure. The fatigue lifetime may be extended after cracking occurs by means of fatigue crack repair. A better insight by means of Finite ElementModelling (FEM) can help in understanding the effects of a repair...master thesis 2017

Tuls, J.J. (author)Composite steel-concrete floor systems consist of a trapezoidal shaped steel deck, reinforcement and cast-in-place concrete. Depending on the span, height restrictions and application shallow or deep decks can be chosen. The shallow deck used within this thesis is the ComFlor75. Due to the low self weight, a bundle of steel decks can be lifted...master thesis 2017

van Erp, P.P.F. (author)The horizontal shear capacity of steel-concrete composite floors can only be determinedwith full scale experiments since no good theoretical model is available. Since the properties of the sheeting can change over time due to wear of the rollers, regular testing of the steel concrete slabs is therefore necessary. The last research on the ComFlor...master thesis 2017

Rikken, M.R.A. (author)Fulfilling our energy demands with renewable resources is one of the world’s greatest current challenges. Building offshore wind farms and using wind energy is one option to achieve this goal. The cost efficiency of offshore wind farms is still limited however, due to high construction and maintenance costs. Several research and development...master thesis 2016

Oomen, S. (author)Several topics related to lifting gantries have been studied. These are the modelling of the structure, the structural behaviour of the gantry, the input parameters of the model and the standards used for the design. A hand calculation model, based on the analysis of built-up compression members in EN 1993-1-1, has been developed that describes...master thesis 2016
