In this paper, identification of energy dissipation in the joints of a lab-scale structure is accomplished. The identification is carried out by means of an energy flow analysis and experimental data. The devised procedure enables to formulate an energy balance in the vicinity of the joints to obtain local energy dissipation. In this paper, a...

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...

Building Integrated PV (BIPV) is considered as a key development for successful deployment of PV in the built environment. However, the effect of PV integration on environmental impact is not fully understood. In this study a single indicator for environmental impact assessment of BIPV is investigated in the Netherlands. A BIPV rooftop with 24...

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...

In this paper simplified expressions for assessing fundamental frequency and modal damping of high-rise buildings taking into account the soil-structure interaction (SSI) are proposed. To this end, several steps have been followed. First, a 3DoF model is formulated making use of dimensionless parameters. Second, the 3DoF model is simplified into...

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...

Voor de bevestiging van dakbedekkingen worden in Nederland specifieke rekenregels gegeven via NEN 6707 en NPR 6708. Dit betreft zowel de regels voor de bepaling van de windbelasting als methodes om de sterkte te bepalen. Deze regels zijn voor zowel hellende als platte daken afgeleid uit resultaten van onderzoek dat in de laatste decennia in...

The aim of this paper is to identify the local energy dissipation in a lab-scale structure by means of the energy flow analysis. In most of the existing approaches the damping is identified either in terms of the modal damping factors or at the material scale. In this paper, an alternative method to these global and material-based approaches by...

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...

De toepassing van zonne-energiesystemen op hellende daken neemt een grote vlucht. Niet alleen nieuwe daken worden van zonnepanelen en zonneboilers voorzien, ook op reeds bestaande daken worden zonne-energiesystemen aangebracht. De bevestiging van deze systemen moet zodanig zijn ontworpen dat deze de belastingen als gevolg van het eigen gewicht,...

De gebouwschil wordt steeds meer gebruikt voor de opwekking van energie. Dit is dan ook een gebied waar veel innovaties mogelijk zijn. Diverse partijen zijn hier druk mee bezig. In het kader van de Dutch Green Building Week toonde TNO op 28 september 2016 tijdens het minisym-posium 'Energie producerende gebouwde omgeving' de laatste ontwikkelingen

This paper presents a new formulation of the Rate Type Compaction Model (RTCM) for sandstone based on the isotach concept. The RTCM was originally developed to explain the loading rate dependent compaction behaviour observed in laboratory test on unconsolidated and consolidated sandstone samples and the delayed subsidence behaviour above...

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...
