Optimized shapes for textile reinforced concrete structures - design of the barbecue furniture 'Donauwelle'

摘要

New solutions in the building industry are required to counteract the steadily increasing consumption of natural resources and the increasing environmental pollution. One approach is to enlarge the application area of concrete by using textile reinforcement. Textile reinforcement is very rangy and non-corrosive and allows therefore a crucial reduction of the concrete cover. Thus, concrete structures with smaller thicknesses can be realized. If the planning architect and the civil engineer work together in an interdisciplinary team to design lightweight structures, a big amount of natural resources can be saved. With this concept the authors of this paper won the competition for the new design of the barbecue furniture for Vienna's Danube Island with the project "Donauwelle". The competition was organized by the City administration of Vienna (MA45) and the Austrian cement industry association (VOZ). In the first part of the present contribution the form finding process is explained. In the second part additionally performed preliminary tests, the verification concept, the static calculations and the production process are presented.
