A shaking table experiment was performed to study the influence of several building products on the out-of-plane behavior of load-bearing walls in one-way bending. The products that were investigated are a high-strength mortar (Remix/Strating), a mortar-less dry-stacked masonry system (ClickBrick), a renovation anchor tie system (Fischer), and...

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...

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...

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...

The AutoR-project takes a holistic approach to reduce the cost of heliostat fields: Wireless control and energy supply enables to use smaller heliostats which need less steel per mirror area (but usually have high wiring cost). A low cost but high efficient drive system is chosen which reduces energy consumption to a minimum amount and leads to...

Integration of PV in the Building Envelope (BIPV) is one of the four key developments necessary for large market PV penetration, together with PV efficiency improvement, price decrease and electricity storage [1]. In the course of BIPV development, Real-Life Lab demonstration projects are realized worldwide to contribute to this goal. In the...

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...

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

The provisions for wind loads on flat roofs differ considerably between current wind loading standards in different jurisdictions. For a number of major wind loading codes, both the definition of roof zones, and the values applied to determine the wind loads are discussed. This paper concentrates on the wind loading zones near edges and corners,...

The new generation of tall buildings is higher and more slender than the buildings built before. Additionally, increased use is made of high-strength materials which have a higher strength yet the same stiffness properties as conventional materials. Both aspects increase the sensitivity of tall buildings to dynamic behaviour. The design has to...

Solar energy systems are becoming increasingly popular. A large potential for these systems is found on buildings, in particular on roofs. For existing buildings with pitched roofs, stand-off systems, which can be applied as retrofit solutions, are frequently applied. Wind loads for such systems are not found from current codes and standards. A...

This paper describes two full-scale experiments in which the pressure distribution over the layers of brick masonry cavity walls is studied. The first experiment focuses on the specification of the wind loads on both outer and inner leafs of these walls. The second experiment is set-up to find a model to describe the transport of moisture, heat...
