Invloedslijnen voor platen: Ingenieurstool op basis van het balkjesmodel

In het vakgebied van mechanica vormen invloedslijnen een tool waarmee gemakkelijk maat-gevende krachten, momenten en verplaatsingen kunnen worden gevonden. Echter, deze invloedslijnen zijn alleen toepasbaar op balken (één-dimensionaal). Binnen de civiele sector zijn naast balken, ook platen een veelgebruikte constructievorm (twee-dimensionaal)....

Connection between concrete columns and continuous floors with integrated steel beams

This research studies a simplified connection between one storey high concrete columns and the continuous floors with an integrated steel beam, of the THQ type, carrying hollow core slabs and covered by a reinforced structural screed. The final goal is to determine the strength of the connection. This is done with a calculation method, which may...

Hollow Core Cross-Laminated Timber: Optimized for a more efficient use of material

Wood is an important building material that has been used for thousands of years throughout the world. It is the most widely used building material and due to its characteristics suitable for a wide range of applications. Still, for the last century steel and concrete have been the materials of choice for large buildings. Part of the reason for...

StructuralComponents 6: An early-stage design tool for flexible topologies of mid-rise concrete buildings

The development of computational tools to aid with early-stage design of buildings is an emerging topic of great value. Developing a good conceptual design for a building is important because it can save a great amount of time and resources over the entire building process. This report discusses the project StructuralComponents 6, a continuation...

Feasibility study of a wood-concrete hybrid super tall building and optimization of its wind-induced behaviour: A case study on a skyscraper in the city-centre of Rotterdam

The demand for sustainable high-rise buildings is growing. Such sustainable high-rise could be realized by the use of mass timber for the structural design instead of more conventional building materials such as steel and concrete. Timber is a renewable resource which can be CO₂ neutral if reforestation takes place to close its carbon...

Influence of various boundary conditions on local buckling of steel tubular piles: Effects of restraints, imperfections and residual stresses

The main focus of this thesis is the influence of different real boundary conditions on the failure mechanism of local buckling of steel tubular piles. The research was started with the theoretical method of describing boundary condition by specifying the degrees of freedom per boundary condition. The method makes use of the radial, meridional...

Strength influencing parameters of iroko glued laminated timber

As timber is being used for several millennia as construction material, glued laminated timber (glulam), a highly engineered timber product, exists for about hundred and fifty years. In Europe, it is nowadays common practise to make glulam from softwood species, though in the last few decades glulam made from different kinds of hardwoods emerged...

Probability of damage of masonry structures due to external ground vibrations

The SBR richtlijn A states threshold values for the vibration speeds causing a 1% probability of failure of masonry structures. These threshold values are very useful for structural designers, because during the construction of new structures or the demolition of existing structures, it is important to know if these structural vibrations can...

Effects of residual stresses on the fatigue crack propagation of an orthotropic steel bridge deck

Orthotropic steel decks (OSDs) are susceptible to fatigue failure due to cyclic loading by heavy traffic passing the deck. These cyclic loads can cause fatigue cracks in the rib-to-deck joint. In and around the joint residual stresses are present due to the welding process. In this thesis, the effects of residual stresses on the fatigue crack...

Combined Actions: Investigation on Widened Deck KW03.01

Structures may be subjected to both mechanical loads and imposed deformation. On one hand, the mechanical loads include, for example, the self-weight of the construction work, the action from normal use by person, furniture and movable objects, vehicles, snow, wind, execution, etc. On the other hand, when the deformation of a structure is...

Modelling a gravitational launch of gravity based foundations for offshore wind turbines

This thesis focuses on modelling a gravitational launch of gravity based foundations (GBF's) for offshore wind turbines. This is an extension of the Blyth Offshore Demonstrator project by BAM Infraconsult. To become more competitive in the offshore wind energy market, the construction of self-buoyant GBF's installed using the `float and submerge...

Numerical modelling of dowelled connections in Laminated Veneer Lumber

The complex mechanical behaviour of timber makes it hard to predict the failure modes in connections made of timber in Finite Element Models (FEM). The combination of various failure modes (brittle and ductile) , anisotropic behaviour, contact of steel elements and large deformations that can occur in a timber joint challenges the use of FEM. To...

Moving load on guide works during a brush collision with a vessel

In the vicinity of locks and bridge piers, guide works are placed in order to steer inland navigation vessels through a narrowed passage. The design of these structures is generally done in a static way, thus without consideration of time-dependent phenomena. By treating the contact force during a brush collision as a static force, several...

Engineering Models for Shear Crack Width and Shear Deflection in Slender Reinforced Concrete Beams

Shear cracking in slender reinforced concrete beams with thin webs can result in significant shear crack width and deflection which is usually ignored in practice due to lack of availability of the engineering models in design codes. This can lead to unconservative predictions of the crack width and total deflection in the SLS (Serviceability...

Estimating the (remaining) service life of timber bridges with the use of factor methods: And incorporating these methods in the calculation of the total costs of ownership

Timber bridges are much applied structures in the Dutch landscape. In contrast to the other two most common building materials, concrete and steel, the use of timber is however almost exclusively limited to bridges for lighter traffic, e.g. pedestrians and bicycles. Examples of timber traffic bridges in Germany, Scandinavia and even in the...

Application of vertical profiled mortar connections in precast concrete shear walls

This thesis focusses on the application of vertical profiled mortar connections in precast concrete shear walls that are built up with a stacked element configuration. The goal of the project is to develop a practical modelling approach in order to be able to apply the connections in a FEM model for structural analyses. For this purpose several...

General formulation of equivalent moment factor for elastic lateral torsional buckling of slender rectangular sections and I-sections

In the past decades, great progress has been made in analyzing lateral torsional buckling of slender beams. The phenomena has been accurately described by differential equations, closed form solutions are available for specific cases and the solution for any load and any boundary condition can be obtained by finite element analysis. Timber and...
