Research on the combination of water and membranes as sound insulation building material
Full text linkp. 3034-3040This research concerns a 200 mm thick panel filled with water. The airborne sound
insulation of this panel was measured in accordance with standard ISO 140-3 [2]. Results
show that the single number rating for the airborne sound insulation Rw [3] for an average water layer thickness of 200 mm is 48 dB. This value is comparable to the one of a 150 mm brick wall or 100 mm concrete panel. Predictions about sound insulation of the same system at different thickness and possible applications such as highway sound barrier or construction site sound barrier are presented in the following pagePronk, A.; Maffei, R.; Martin, H.

Research on the combination of water and membranes as a structural building material
Full text linkp. 3024-3033The aim of this paper is to investigate the combination of water and membranes for
temporary architectural applications.
Water as a construction material, can be useful for three different purposes: first of all,
thanks to its thermal mass, it can be used as a medium for cooling down or heating up
buildings (Pronk et al [6]); secondly water is uncompressible and, in combination with air,
can be used as part of a structural element; thirdly the mass of water could work as a sound barrier so it can be used as sound insulation material (Rodrigues and Coutinho [7]).
This paper shows the result of the structural behaviour. There is another paper about sound insulation properties of water. The research in both structural and sound insulation fields was carried out in the laboratories of Technische Universiteit Eindhoven, The Netherlands.
The prototype is a "waterbeam" of 2 m span. Starting from the Tensairity(R) technology
principle (Luchsinger et al [8]) developed by Airlight, the purpose of this experiment is to
replace the iron struts with a second membrane chamber filled with water. Water works
well in compression and air prevents buckling. The result is a rigid structural element made by non-rigid material (water, air, membranes and cables) with a significant reduction of weight and cost of transportation compared to the traditional iron beam but also compared with the Tensairity(R) system. Different bending tests were carried out. In each test, the two chambers of the beam were filled with air or water to understand the material behaviour.The comparison between the results shows that water works slightly better than air (stiffness increase of a range of 8-13% in the elements filled with water).
Water application in architecture showed promising results. Further investigation (pure
compression tests on columns, multiple layers sound barrier) should be carried out. These results could give architects new design opportunities and solutions concerning temporary buildings and moveable architecture. Moreover the company and building construction industry could develop innovative structural elements and new insulation components.Pronk, A.; Maffei, R.; Martin, H. (2009).

Heat adapting membrane
No full textThe most usual way for cooling a tensile structure is by using different layers. The air between the layers is used as an isolating material. When the air in between the layers has become too warm, it can be ventilated away. Another way is the use of a phase changing material in the membrane. In a moderate climate this will be sufficient. When a higher capacity is required, the temperature problems of tensile structures are solved by heating or cooling air. Conditioning a tensile structure in this way is not as efficient as by the use of a radiation surface. Therefore we developed a textile radiator that is capable of adapting 500W/m2

ARCHIMEDIA consists of projects and products to make architecture possible as a medium and embodiment symbol of uniqueness, identity and personality of the user or inhabitant instead of architecture as an excuse to create an ecstasy of visual, technical and esthetical abilities

Full text linkQuantifying structural flexibility for performance based life cycle design of builidings
No full textWhen we try to specify minimum performance levels for the whole life cycle of a building we have to face the problem of how to deal with the uncertainties of future functional use. In stead of specifying minimum functional requirements we could opt to specify minimum levels of flexibility. To achieve this, it becomes necessary to quantify and compare flexibility . To do this flexibility is defined more precise. Because the building structure is usually the longest lasting building layer the possibilities to quantify the flexibility of the building structure, Structural Flexibility , is looked at in more detail. A definition of Structural Flexibility is given and a framework to measure and compare Structural Flexibility is discussed
