Der von SOMA Architecture aus Wien, Österreich entworfene Themenpavillon “One Ocean” ist eines der wichtigsten Gebäude der Expo 2012 in Yeosu, Korea. Die dem Expo‐Gelände und dem Haupteingang zugewandte Seite ist von einer kiemenartigen, mit LED bestückten beweglichen Medienfassade geprägt. Sie stellt einen gestalterischen Bezug zum Meer her und ermöglicht die Lichtsteuerung des Gebäudes.Grundlage der Entwicklung der kinetischen Fassade war die Analyse natürlicher Bewegungsprinzipien. Die Verwendung von glasfaserverstärkten Kunststoffen (GfK) erlaubt große reversible elastische Verformungen und ermöglicht somit eine komplett neue Interpretation wandelbarer Strukturen.Bio‐inspired kinetic façade for the thematic pavilion “One Ocean” EXPO 2012 in Yeosu, KoreaThe Thematic Pavilion “One Ocean”, designed by SOMA Architecture, Vienna, is a major and permanent building for the Expo 2012 in Yeosu, Korea. The façade facing the expo area and the main entrance is conducted as kinetic media façade symbolizing the gills of a fish. The façade therefore illustrates the theme of the Expo “The living ocean and coast” very well.Development of the kinetic media façade was inspired by flexible deformation principles found in plant movements. The project is a role model for a novel application of glass fiber reinforced polymers (GFRP) for deployable structures as well as for advanced biomimetic research and design.
The use of lightweight and corrosion-resistant construction materials such as pultruded glass-fibre-reinforced polymer (GFRP) profiles in bridges has been increasing in recent years. Even though the use of detachable connections with mechanical fasteners is the most reliable and controlled technique for joining GFRP structures, there is a lack of information on the load-bearing capacity of connections in which the bolts are subjected to tension loads.The results from a series of tests aimed at investigating the load-bearing behaviour of different GFRP connection types where bending or pull-out failure may occur are summarised in this paper. The tests were conducted using standard stainless steel bolts and nuts. Load resistance models are proposed based on the experimental investigations. Furthermore, a partial safety factor is determined using the statistical methods given in EN 1990. Finally, an application of mechanically fastened connections is shown for a GFRP pedestrian bridge erected near Schwerin, Germany.
Curved glass is increasingly used in modern architecture, driven by free‐form design, the desire for smooth, continuously curved facades and new or improved manufacturing methods. Permanent curvature is obtained by thermal bending, whereas elastic cold bending results in a reversible curved glass shape stabilized either by fixing upon a substructure or by lamination with shear‐stiff interlayers. However, for the application in building projects many mutually depending factors such as the achievable geometrical shape and curvature, glass dimensions, potential residual stress, load bearing behavior, applicability for IGUs, coating options, cost, necessary supports, lamination, interlayer type or the optical quality have to be respected. The present paper contributes to creating a design basis regarding the use of curved architectural glass by comparing the typical properties, assets and limitations of the above‐mentioned types and by illustrating their application through project examples.
Durch die Digitalisierung verändern sich unser Leben, unsere Gesellschaft und ganze Wirtschaftszweige. Sogenannte Disruptoren wie Apple, Google, Uber und viele andere führen in kürzester Zeit zu einer Neuordnung einer Branche. Beispiele für disruptive Technologien sind unter anderem die Digitalkamera, das Smartphone, das Elektroauto und eben auch das CAD (Computer Aided Design), das in den 90er Jahren die technische Handzeichnung mit Tuschestift und Zeichenbrett innerhalb kürzester Zeit ersetzte (Bild 1). Digitaler Prozesswandel, das parametrische Entwerfen und der Einsatz von BIM als Planungsmethode führen vermehrt auch im Bauwesen zu grundlegenden Veränderungen in den Planungsprozessen und Planungsschnittstellen. Sie ermöglichen die Planung, Berechnung und Umsetzung deutlich komplexerer Bauwerke, führen zu durchgängigen Prozessketten zwischen Planung, Ausführung und Nutzung, und ermöglichen die koordinierte Bündelung aller Bauwerksinformationen in einer Projektdatenbank. Durch die Veränderung unserer Prozesse hin zu einer teamorientierten Planungsmethode lassen sich Paradigmen aufbrechen und Fehlentwicklungen korrigieren. „Aber dafür müssen wir heraus aus der Deckung, selbst ausprobieren und mit reden [1]”.
