The last decade has seen a growing interest in cohesive zone models for fatigue applications. These cohesive zone models often suffer from a lack of generality and applying them typically requires calibrating a large number of model-specific parameters. To improve on these issues a new method has been proposed in this paper based on the Thick...

Fatigue is one of the main design drivers for offshore wind substructures. Using Fracture Mechanics methods, load sequence effects such as crack growth retardation due to large load peaks can be included in the fatigue damage estimation. Due to the sequence dependency, a method is required that represents the sequences of loads in the design or...

The Fatigue Ductile–Brittle Transition (FDBT) is a phenomenon similar to the fracture ductile to brittle transition, in which the fracture mode of the fatigue cracks changes from ductile transgranular to cleavage and/or grain boundary separation. Fatigue at temperatures below the FDBT has a much different crack growth rate than fatigue above...

Despite extensive developments in the field of Acoustic Emission (AE) for monitoring fatigue cracks in steel structures, the implementation of AE systems for large-scale bridges is hindered by limitations associated with instrumentation costs and signal processing complexities. This paper sheds light on some of the most important challenges in...

In this paper, a damping model for a high-rise building is introduced. This model is used to investigate the possibilities to identify the relative damping contribution of the internal material damping in building elements, energy loss at element interfaces and energy outflow at the interface with the ground. The building is modeled as an Euler...

Pressure measurements were performed on various configurations of two high-rise building models in two atmospheric boundary layer wind tunnels in the Netherlands. A comparison was made of the interference factors of the minimum and maximum peak pressures over all pressure taps at 0 degree angle of incidence obtained for measurements on the...

De windbelasting op gevelsystemen wordt mede bepaald door de detaillering van het gevelsysteem. Wanneer de gevel bestaat uit een meerlaagse constructie met een luchtdicht binnenblad, een spouw en open voegen in de buitenste laag, kan drukvereffening optreden. De mate van drukvereffening heeft consequenties voor de belasting op het buitenblad. In...

Een congres over de toekomst van het hellende dak, op een historisch stoomschip dat vroeger mensen vervoerde naar de 'Nieuwe Wereld': het SS Rotterdam bood op 13 november een passende ambiance voor het Nationale Congres van branchevereniging HHD. Het werd een middag over de lange zoektocht naar een passende pan, over NEN7250, de noodzaak van...

Pressure measurements on a square plan form high-rise building model and two square high-rise building models in side-by-side arrangement were analysed using the Fast Fourier Transform (FFT) to define peak frequencies resulting from interference. For the isolated building model, a reduced frequency fred = fB/UH = 0.08 was determined on the side...

Door de nog altijd toenemende rekenkracht van computers komen op vele werkterreinen steeds geavanceerdere modellen beschikbaar. Voor de bepaling van windbelastingen op gebouwen wordt echter nog altijd gebruikt gemaakt van oude methoden: normbladen en windtunnelonderzoek. Uiteraard zijn die doorontwikkeld maar een doorbraak van een rekenkundig...

Forces on multi-span gable roof buildings with different height/width ratios have been measured to investigate the effect of the number of bays on the horizontal component of the wind force. It has been found that with increasing number of bays, the horizontal wind force increases proportionally

Wat is de invloed van een gebouw op de windbelasting van de gevel- en dakelementen van een nabijgelegen gebouw? Het antwoord op die vraag is van belang voor een veilig ontwerp van gevel- en daksystemen. Okke Bronkhorst onderzoekt deze invloed in het kader van zijn promotieonderzoek aan de Technische Universiteit Eindhoven

A series of wind tunnels tests are presented on a cube, equipped with a permeable outer layer. The influences of cavity depth and opening width have been investigated. This research shows that a wind direction of 75 degrees with respect to the considered panel gives the highest differential pressures relevant for cladding. For smooth approach...

Voor de bepaling van de windbelasting schieten de normen soms tekort. Bij afwijkende gebouwvormen of omgevingssituaties zijn er alternatieve bepalin gsmethoden voorhanden: op schaal in de windtunnel, op ware grootte of via numerieke simulatie. In een meerjarig onderzoek wordt met de drie methoden informatie verzameld om betere...

Pressure measurements on the surfaces of a high-rise building model with height h = 0.48 m and width b = 0.12 m were performed in a boundary layer wind tunnel. Experiments were carried out for an isolated model and for three configurations with an interfering half-height building model. The effects of the interfering building to the minimum peak...

Particle Image Velocimetry (PIV) and pressure measurements were performed on a highrise model with a height (H) of 0.48 m and a width (B) of 0.12 m in a turbulent atmospheric boundary layer. Experiments were carried out for an isolated model and four tandem configurations with varying separation distance (S) between the models. Mean and standard...

In general the condition of a structure can be assessed in terms of a performance indicator. For example, this can be the strength of a structure. An asset manager is concerned with ensuring that the performance of a structure does not fall below a given minimum level. This can be achieved by inspecting or monitoring the structure. As the...
