Title:	Ultraleichtbau
Abstract:	Das Entwerfen im Leichtbau ist die Suche nach dem Leichtestmöglichen. Es ist das Herantasten an das physikalisch und das technisch Machbare und damit auch das Arbeiten an den wissenschaftlichen Grenzen. Mit dem vom Autor entwickelten Ultraleichtbau kann man die Grenzen des Leichtestmöglichen weit hinausschieben. Neben der Reduktion des Materialverbrauchs auf ein bisher nicht für vorstellbar gehaltenes Minimum wird es im Ultraleichtbau auch möglich, Verformungen zu reduzieren und Schwingungen unter dynamischer Beanspruchung zu dämpfen - ein enormer Fortschritt, der sehr interessante Perspektiven für das Bauwesen eröffnet. Der vorliegende Artikel beschreibt zugrundeliegende theoretische Überlegungen und präsentiert diverse Experimentalbauten, die das Potential des Ultraleichtbaus eindrücklich vor Augen führen. Ultralightweight Structures. The search for lightweight constructions is the search for boundaries. Designing the lightest possible constructions can be equated with feeling one’s way towards the limits of what is physically and technically possible. It is about the aesthetics and physics of the minimal, and it is about stepping across the dividing lines between scientific disciplines. Using the concept of Ultralightweight Structures developed by the author, it becomes possible to reduce the use of material to a minimum hihterto considered unachievable. Moreover, it leads to the reduction of distortions and helps to dampen vibrations - an enormous progress opening up interesting new perspectives for architecture. The present article describes the theoretical considerations underlying the concept of Ultralightweight structures and presents a selection of experimental structures demonstrating the potential of this new concept.
