The library of the University of Chicago is currently extended by means of a building directly adjacent to the existing library. The extension building called Mansueto Library designed by Chicago-based architect Helmut Jahn - is covered by an all but dematerialized glazed steel grid shell spanning over the reading room. The translational shell is 36.5 m wide and 73 m long. It is clad with fritted insulated glass units lying on minimized aluminium extrusions. The building includes further special structures, such as a 20 m long glazed steel bridge; this bridge connects the new library with the existing building. Another interesting special structure is the row of glazed study rooms: the walls of these rooms are fully transparent due to the use of glass as a loadbearing element. The present article gives an overview of the design and construction of the grid shell and the other special structures. © Ernst & Sohn Verlag für Architektur und technische Wissenschaften GmbH & Co.

Reducing the environmental impact of concrete structures is a significant step for a sustainable building industry. Mass reduction due to an application of high-tech material combined with a focus on design for recyclability of structural elements requires the development of new construction methods. The use of Ultra- High-Performance Concrete (UHPC) with its advantageous properties allows for the construction of thin walled, prefabricated elements and aesthetically pleasant structures. Requirements for the assembly, disassembly and therefore recyclability as well as the compensation of tolerances and the accessibility of the gap between joined structural elements have to be taken into account for joining prefabricated elements on site. The authors present a construction method under consideration of the aforementioned requirements for joining thin, prefabricated elements made of Ultra-High-Performance Fibre Reinforced Concrete (UHPFRC) by the use of implants. The implant development, first results of experimental investigations and a general outline on the design for assembly and disassembly will be given in the context of recyclable and sustainable structures. © 2011 Ernst & Sohn Verlag für Architektur und technische Wissenschaften GmbH & Co.

The investigations and experiments carried out at ILEK show the potential of multilayered textile building shells as useful, high-end, climatic systems for the building sector. In further research projects, which have begun in the meantime, questions relating to the acoustics of rooms and urban spaces will be studied in order to develop possible solutions for shell structures with optimised acoustic features./9/At same time, extensive work will be carried out into incorporating a number of textile layers or functional materials into suitably shaped frames./8/.

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. © 2014 Ernst & Sohn Verlag für Architektur und technische Wissenschaften GmbH & Co.
