With the ongoing development of advanced textiles and smart materials, promising new possibilities are emerging in the field of building cladding systems. The flexibility, translucency, and unique aesthetic characteristics of high-performance textiles present a wide range of architectural potential, while their light weight, simplicity, and typically discrete construction offer significant advantages with respect to recyclability and sustainable design. Designed with care, textile materials have the potential to revolutionize the building envelope, in the form of multilayer adaptive textile cladding systems. This article will explore the challenging requirements which must be met by these systems, explain the concept of multilayer textile- and film-based envelopes, and describe their unique behavioural characteristics in the building science context. The need for accurate material property characterization and advanced simulation techniques will also be discussed.

The Baku Flame Towers Project is a recently completed three-tower mixed use development in Baku, the capital of Azerbaijan. The shapes of the three towers refer to the flames of a fire, which has high importance in that country due to the huge amount of existing oil wells. The present article deals with the special challenges of façade and special structures engineering of this geometrically complex project. Only the close collaboration between the design specialists made a successful project for all participants possible © Ernst & Sohn;.

Many building structures are designed in such a way that the deflection in a critical point of the structure is reduced as much as possible (e. g. the middle span of a bridge or the top level of a high rise building). This often requires a lot of material. In addition optimizing these kinds of structures by hand is quite difficult and time consuming. This article demonstrates the practical usage of an optimization method (called MVM), which allows an engineer to redistribute the material within a geometrically given structure in such a way that the deflection in a critical point is reduced as much as possible. The demonstrated case studies are a steel truss bridge over four spans and a steel roof structure for a bus station. © Ernst & Sohn;.

In the context of a research project at the Institute for Lightweight Structures and Conceptual design (ILEK) at the University of Stuttgart an innovative connection technique for structural glazing was investigated. The connection technique consists of a metal insert partially embedded in the interlayer (Sentry Glas), such that the interlayer acts as the adhesive for the structural connection. Besides investigations of the short-term load-bearing behaviour and the corresponding numerical simulation, the load-bearing behaviour under long-term loading is very important for a comprehensive characterization of this connection method. This paper describes the investigations that were conducted with respect to the long-term behaviour and presents the experimental results. © 2013 Ernst & Sohn GmbH & Co. KG.


The KfW bank group in Frankfurt is one of the main supporters for energy-efficient construction in Germany. Their new Headquarters was equipped with the latest design and technical innovations. A major element of the energy efficiency concept is the multi-colored, shingled, double-skin façade, making it one of the first highrises with an annual primary energy consumption of less than 100KWh per sqm. The KfW Westarkade was awarded "Best Highrise of the World 2011" by the renowned CTBUH, Chicago. © 2013 Ernst & Sohn GmbH & Co. KG.

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.

The new headquarter of the HDI Insurance Group in Hanover was designed by architect Christoph Ingenhoven. It offers maximal user comfort and minimal consumption of energy and resources. An important precondition for the open, transparent appearance of the building is the filigree load-bearing structure designed and engineered by Werner Sobek (Frankfurt/Stuttgart). The following article describes the most important specifics of this structure. Copyright © 2013 Ernst & Sohn Verlag für Architektur und technische Wissenschaften GmbH & Co. KG, Berlin.

A new underground central train station will allow for the integration of Stuttgart into the growing network of high-speed rail traffic in Europe. It follows ecological, economic and technological parameters and provides comfort and security. Its structure is characterized by an elegant concrete-shell construction. The intelligent use of natural energy resources avoids CO 2 emissions. The structure and the lighting cones connect the platform level with the square and park above. Varied and broad views along with the elegance of the supporting structure give the station its unmistakable identity. The form of the modular shell supports is based on a reversed-suspension model. The current railway station and the new underground station will be the nucleus of the new urban development of "Stuttgart 21" and will create an interface between the old and new city. The Schlossgarten (palace gardens) remains the green heart of Stuttgart and will only gain in importance as the city expands. Some of the existing rail yards will become part of the park. The historical station building will function as a loggia with its tower continuing to be a major landmark. The new station and the new urban district will give Stuttgart a new centre. © 2013 Ernst & Sohn Verlag für Architektur und technische Wissenschaften GmbH & Co. KG, Berlin.
