GM Football – Eingangspavillon des Headquarters von General Motors in Detroit

GM Football – Vestibule of the General Motor's Headquaters, Detroit. The article describes the construction, production and erection scheduling of a glazed vestibule over an elliptical, i.e. football‐shaped outline of 30 m length and 10 m width. The point supported glazing of the 14 m high façade is supported by a spatial cable net structure, which stretches in vertical direction from the spatial fish‐belly girder to the ground and in horizontal direction between the cable sagged columns at the tapered corners of the building. While workshop planning of this biaxial curved cable net structure, beside the aesthetic requirements, it was also necessary to consider the mountability and adjustablity, as well as the development of a conclusive assembly concept and the pertinent computations.

Safety against formation of through cracks of profiled fibre-reinforced cement sheets for roofing

Loads due to wind, snow or traffic on a roof determine the requirements to the strength and stiffness properties of profiled sheets for roofing. Apart from these loads, locked-in stresses can occur due to differences in temperature and moisture strains in the profiled sheets and the wooden laths supporting the sheets. These tensile and compressive stresses are induced in the sheets if they are firmly fastened to the laths with fastening screws.The purpose of this investigation was to analyse the safety of the profiled sheets in transmitting these loads without the formation of through cracks.The analysis is based on an experimental and a theoretical investigation of the strength and stiffness properties of unexposed profiled fibre-reinforced cement sheets and of sheets that had been exposed on a roof in three years.

Fassaden‐ und Dachkonstruktionen für ein Kernkraftwerk

Für den Neubau eines Kernkraftwerkes mussten bei den Fassaden‐ und Dachkonstruktionen verschiedene besondere technische Aufgabenstellungen bewältigt werden. Diese sind zum einen in den lokalen klimatischen Verhältnissen begründet, zum anderen wird mit dem Neubau eines Kernkraftwerkes ein besonderer Anspruch hinsichtlich Betriebssicherheit verbunden. Die statisch‐konstruktiven Beanspruchungen, die Anforderungen aus der Bauphysik sowie die Montagebedingungen erforderten die Weiterentwicklung etablierter Fassadenaufbauten und deren Prüfung in Laboren und Prüfinstituten vor Fertigungsbeginn. Thema des Aufsatzes ist die bereits weitgehend realisierte Gebäudehülle des nichtnuklearen, konventionellen Bereiches – dem “Turbine Island“. Züblin Stahlbau GmbH, Mitglied des IFBS und DStV, führte im Turbine Island neben den Fassadenarbeiten auch die Stahlbauarbeiten aus. Aus der Verbindung beider Gewerke wurden Synergien insbesondere in der Planung der Schnittstellen und der Verzahnung von Montageabläufen vor Ort gezogen. In Summe werden beim Turbine Island ca. 90000 m² Profilbleche verlegt und ca. 4000 t Stahlkonstruktionen montiert. Facade and roof construction for a nuclear power plant. For the new building of a nuclear power plant, different special technical problems are to be handled with regard to the facade and roof constructions. On the one hand, these are caused by the local climatic conditions, while on the other hand a special demand with regard to operational safety is associated with the new building of a nuclear power plant. The static‐construction demands, the requirements from the construction physics and as well as the erection conditions required the further development of established façade structures and their testing in laboratories and testing institutes before production commencement. The already largely realized building envelope of the conventional area – the “Turbine Island” – is the subject of this paper. Züblin Stahlbau GmbH, an IFBS and DStV member, also implemented the steel construction works in the Turbine Island, as well as the facade work. Synergies were generated from the combination of both trade sectors, in particular in the planning of the interfaces and the intermeshing of assembly process sequences on site. In sum, with the Turbine Island, approx. 90000 m² profiled sheet metal units are laid and approx. 4000 tons steel structures mounted.     

Bauen im Bestand – Lösungen für Dach und Fassade in Stahlleichtbauweise

Building redevelopment – Solutions for roof and façade using lightweight steel construction . The research project ”Building redevelopment – Solutions for roof and façade using lightweight steel construction“ investigates possibilities to improve energetically existing roof and façade systems in lightweight steel and massive construction by using lightweight steel systems. As refurbishment systems steel sandwich panels as well as modular lightweight steel constructions, consisting for example of steel supporting profiles, thermal insulation and steel sheet profiles, will be applied. Besides hygrothermal‐building‐physical studies also static‐mechanical reviews for the energetically optimized building systems will be conducted. The present paper shows selected results that have been developed within the project. On the one hand, the energetic quality of existing façades in lightweight steel construction is shown, and savings potentials due to heat transmission, which are opened up by the renovation of these façades, are clarified. On the other hand, some of the resulting building‐structural questions with regard to load‐bearing behaviour and loadings are discussed.

Sandwich‐Dachbauteile für Flachdächer

Sandwich panels for roof covering. Sandwich panels for roof covering, which are currently used, are in principle always equipped with a trapezoidal profiled face. It is because of this geometry that the longitudinal joints of the panels are easy made by overlapping the external metal faces. The bending stiffness of these profiled faces also largely avoid the increasing in deflection caused by creep effects of the core as a result of long‐time loading from snow and self weight. In particular for flat roofs of industrial buildings there are some disadvantages caused by the profiling of the outer faces, e. g. the sealing of openings in the roof. Furthermore the mounting of the profiled panels always have to be realized in the direction of apex to cullis because of the rain water flow conditions. This requirement premises a substructure with purlins. In the described research project sandwich panels with flat faces were developed, where penetrations can be sealed in an easy way and mounting of the panels perpendicular to the roof pitch, from frame to frame (without purlins) is possible. All necessary research was conducted, in particular with regards to creeping effects, sealing of the panel joint and special fixings. On the base of the obtained research results, practice oriented solutions are proposed.     

Wind tunnel study of a cone-like shaped roof: Reynolds number effects

This paper describes the results of wind tunnel tests performed on a cone-like shaped roof characterised by multiple curved surfaces. Surface pressure measurements were carried out by high-frequency scanners. In particular, Reynolds number and surface roughness effects on the mean pressure distribution and on its unsteady components have been analysed. Methodologies were found in order to validate the wind tunnel wind load measures performed on scale models having the typology of building roofs with curved surfaces.
