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...

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...

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...

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...

Een model ontwikkelen waarmee op basis van eigenschappen van de verschillende onderdelen in een gebouw de demping kan wworden voorspeld, is het doel van een recent gestart (promotie-)onderzoek aan de TU Delft. Behalve experimenteel onderzoek op laboratoriumschaal, staan metingen gepland bij Nederlandse hoogbouw. Dit artikel gaat in op de huidige...

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...

A wind tunnel study was performed to assess the influence of interference between two high-rise building models on the minimum peak pressure coefficients on facades and roof. A total of 33 configurations were investigated for 24 angles of incidence. The influence of a square and circular interfering model with a height equal to and halfthe...

The new Dutch standard NEN 7250 ([1], NEN, 2014) gives rules for the building integration of solar energy systems. A considerable part of thís standard deals with the wind loads on systems, placed on pitched and flat roofs. Wind tunnel tests were carried out in 2003 and 2013 to provide values for systems placed on flat toofs. The latter study...

The net wind load on the outer layer of a façade consisting of multiple layers is determined by the external pressure and the cavity pressure. For an air-permeable outer layer, the cavity pressure is dependent on the extent to which the external pressure equalizes over the openings. Minimizing the pressure difference between external pressure...

The influence of interference between two high-rise building models on the minimum peak pressures was investigated in an atmospheric boundary layer wind tunnel. Pressure measur€ments were performed on a square model with an aspect ratio of 1 to 4. The influence of an interfering model with the same height as well as half the height was...
