Wang, Qinyu (author), Senatore, Gennaro (author), Jansen, K.M.B. (author), Habraken, Arjan (author), Teuffel, Patrick (author)This paper presents design and characterization of a new type of structural joint which can vary its stiffness through actuation. Stiffness variation is employed to control the dynamic response of frame structures equipped with such joints. The joint is made of a shape memory polymer (SMP) core which is reinforced by an SMP-aramid composite...journal article 2020

Meinen, Nadieh Elisabeth (author), Maria, Raphaël Daniël Johannes (author), Hofland, Bas (author), Jonkman, Sebastiaan N. (author)Vertical slender hydraulic structures such as sluices, navigation locks, or storm-surge barriers are often dynamically loaded by waves. For a safe and economic design, an accurate description of the wave loads is needed. A widely used formula for this purpose is the Goda–Takahashi wave load formula (GT). It was derived for the assessment of...journal article 2020

Schut, Gerwin (author)The prediction of structural vibrations in vibration sensitive laboratory structures is a complex problem involving computationally heavy 3D models with long computational times. However, in the early design phases of a project long computational times are undesirable. Therefore the problem statement of this Master thesis concerns the...master thesis 2019

Verlinde, Ronald (author)Offshore wind energy is considered a necessary energy resource, that may stimulate the transition from fossil fuels. Following the successful development in Western Europe, offshore wind is quickly gaining momentum in the Asia-Pacific region. At variance with North-Sea based offshore wind turbines (OWTs), structures installed in the Asia-Pacific...master thesis 2019

Mangat, Naunidh (author)Wind energy has emerged as a promising alternative to fossil fuel energy sources over the last two decades partly due to considerable reductions in the cost of power production. A common trend towards cost reduction has been to build larger and lighter wind turbines. These produce more power per unit and use less material. Another strategy for...master thesis 2019

Brakel, Luuk (author)In this thesis a preliminary design is made for a tension leg platform capable of supporting a 10 MW ocean thermal energy conversion (OTEC) plant of the coast of Curacao. The environmental conditions and bathymetry around Curacao are analyzed making use of data from the MERCATOR data base. A suitable location is selected and the 100 year wave...master thesis 2018

Hendriksen, Eduard (author)A project is under way to replace the ferry crossings in Norway's highway E39 with fixed links, such as highway bridges or tunnels. This thesis research is on the crossing located at the Sognefjord, the widest and deepest of the straight crossings in the E39 highway. Previous thesis projects at IV-Consult have yielded a design for a floating...master thesis 2018

Heuberger, Chris (author)Floating bridges are found at locations where deep water must be crossed for a long distance, such as in Norwegian fjords. The superstructure of the existing floating bridges is usually constructed from steel. In a marine environment these bridges are exposed to dynamic wave loads. As such, the current floating bridges suffer severe damage due...master thesis 2018

Djapara, Yosua (author)The trend of the slender and high-rise building has made the structure prone to dynamic loading. This thesis is focused on the dynamic behavior of the high-rise building subjected to wind action. The acceleration becomes a limiting criterion in designing such structure which can be categorized as the comfort criteria of the building. Nausea and...master thesis 2017

Jolink, Chris (author)When modelling a structure-soil system, interaction stresses at the interface of the structure and the surface of soil layer influence the dynamic behaviour of the system. These interaction stresses are not accounted for in many simplified models that evaluate the behaviour of the soil layer and the structure separately. Modelling a fully...student report 2017

van Til, J. (author)Tuned Mass Dampers (TMDs) are passive spring-mass-damper systems that can reduce the fatigue damage in offshore wind turbines, caused by cyclic hydrodynamic loads. The TMD is typically installed within the tower at a high position, where it can attack the first bending mode of the combined structure. In order to calculate the fatigue damage in a...master thesis 2016

Reuver, G. (author)Urban areas in the Netherlands are expending rapidly and civilization is squeezed onto a decreasing space. As a result building projects intent to be located very close to adjacent constructions leading to potential risk damaging these structures. Especially structures that are constructed within the subsurface, like cables and ducts, require...master thesis 2016

Kirschneck, M. (author)The ever growing population of human beings on earth introduces the challenge of providing affordable, sustainable energy for everyone. Emerging markets, such as China, India or Brazil, quench their thirst for cheap energy by fossil fuels and nuclear power. At the same time researchers from all over the globe warn the public of the advent of a...doctoral thesis 2016

Tieleman, O.C. (author)As part of the Afsluitdijk project the discharge capacity, which is currently facilitated by two sluice complexes, is increased to cope with future sea level rise. It was decided to realise this by an innovative solution: the pump gate. The steel lifting gates, each containing three pumps, will be implemented in the existing sluice complex in...master thesis 2016

Bernhammer, L.O. (author)Wind turbines convert kinetic energy of the wind into electrical energy. Unfortunately, this process is everything but constant, as the wind source shows large fluctuations with high and low frequencies. This turbulence, together with the wind shear and yawed inflow, excites the turbine structure, thereby driving the loads and the design of...doctoral thesis 2015

Reimert, Z. (author)In structural design there is a tendency towards more slender and challenging architectural structures. Footbridges become more slender with an increasing high ratio live load to dead weight. A consequence of this increased slenderness of footbridges in an increased susceptibility to human-induced vibrations. The evaluation of the serviceability...master thesis 2014

Van der Valk, P.L.C. (author)Large scale offshore wind power has been recognized as a key technology to increase the share of renewable energy. However, as this energy source is currently still relatively expensive, efforts are made to significantly reduce its costs. Cost reductions are to be achieved, for instance, by installing larger turbines in larger offshore wind...doctoral thesis 2014

(author)Micro Air Vehicles (MAVs) are small unmanned aircrafts which have a maximum size limit of 150 mm in any direction. They can be used for surveillance, reconnaissance, targeting, etc. To perform such missions, MAVs are required to hover.

Van den Bosch, D.D. (author)One way of deriving the dynamics of a structure, is by combining the dynamics of its substructures. This concept is named ’Dynamic Substructuring’ and it allows us to cope with the increasing complexity of models by dividing them into substructures and deriving their structural dynamics independently. This allows an improvement in computational...master thesis 2014
