In recent years, the use of computational fluid dynamics (CFD) to evaluate flow fields has become more popular in various branches of industry. In building design, there is a similar trend towards the increasing use of CFD. There are several guidelines for CFD analysis of flows in the urban environment, e.g. [1-4]. For assessment of wind speed...

An investigation is presented to determine the wind loads on external solar blinds on two 60 m high towers. This investigation was performed some years after the construction of the towers, with the sun blinds in place. A combination of wind tunnel tests and full scale measurements was done. The shape of the towers, and the unique design of the...

An atmospheric boundary layer wind tunnel study was performed to determine the overall horizontal wind load on multi-span duo-pitch greenhouses. The results of this study are intended for the stability design of inflexible Gladding system greenhouses (designated as Class A in EN 13031-1) with roof pitch angles of 23-24' and ridge heights of 7.5...

Wind loads are responsible for a large amount of damage to greenhouses, and are therefore an important factor in the structural design of greenhouses. Previous wind load studies on greenhouses [1-8], have only investigated wind loads on the first 9 roof spans. However, most greenhouses are much larger than 10 roof spans. For these larger...

The wind loads on solar energy systems are crucial for the engineering of the panels, substructure and fixings. There is a demand for aesthetically more acceptable solutions such as frameless solar systems. For these frameless systems, the wind loads are carried by the panels themselves. Combined with the increase in the size of photovoltaic (PV...

Façade elements are themost vulnerable parts of buildings with respect to wind loading. In this paper it is assessed to what extent wind-loaded façade elements fulfill the minimum reliability requirements as set in the Eurocodes. The reliability analysis needed for this assessment should account for the uncertainties in each of the parameters...

Demping is een belangrijk criterium bij het ontwerpen van een draagconstructie van hoge gebouwen. In een promotieonderzoek aan de TU Delft wordt een model ontwikkeld waarmee deze demping kan worden voorspeld, op basis van eigenschappen van de verschillende onderdelen in een gebouw. Behalve experimenteel onderzoek op laboratoriumschaal, staan...

Wind loads on permeable building skins are determined by the pressure difference between the external pressures and the pressures inside the cavity. External pressures are given in current building codes for a wide variety of building shapes, location on the building envelope, effects of detailing etcetera. For the pressures in the cavity and...

Wind-induced pressure differences over rain screens are determined by the external pressures and the pressures inside the cavity. Minimizing this pressure difference decreases the risk of water leakage and also helps to minimize the local loads on the façade elements. Current rules to determine the wind loads on such structures are based on very...

This paper addresses questions that arose during development and application of the Dutch guideline for wind tunnel testing to determine wind loads on buildings. This guideline (CUR 103) is being used since 2005, and a first revision is foreseen. Within this revision, the relation with Eurocode EN 1991- 1-4 is established. Questions to be...

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...

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...

Wind is een belangrijke parameter in het ontwerp van gebouwgevels. In veel gevallen bepaalt de windbelasting de dimensies van de gevelbeplating en de ophanging. Die belasting wordt voor een belangrijk deel bepaald door de mate waarin kan worden gerekend met drukvereffening. Een goede kennis van de windbelastingen leidt ertoe dat gevelsystemen...

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
