P 44 - Steel tracks for the EMS short stator and long stator version The Federal Republic of Germany is a leader in the development of electromagnetic monorail systems. Research funding for electromagnetic monorail systems is provided by the Federal Ministry of Research and Technology. The tracks for electromagnetic suspension railways account for the largest share of the investment costs in the event of realisation; therefore, particular importance is attached to the development of the tracks. The Studiengesellschaft für Anwendungstechnik von Eisen und Stahl e.V. (Study Association for Application Technology of Iron and Steel) has sponsored the present research work in order to develop favourable track systems for electromagnetic suspension railways in steel construction, taking into account all the possibilities of modern steel construction. As a result of this research work, all the necessary track developments in steel construction could be brought to a successful conclusion in addition to the work sponsored by the Federal Ministry of Research and Technology. The research work also provides a summarised overview of the status of track development at the end of 1977. It can be a valuable aid for study purposes and further developments. Elements of the results of these investigations were also used in the first application-oriented test track made of steel at the International Transport Exhibition in Hamburg in 1979. It is to be expected that the possible solutions for rail crossings shown in this research work will be of interest for future applications, especially for bridges with large spans. The research work was carried out on behalf of the Studiengesellschaft für Anwendungstechnik von Eisen und Stahl e.V. by the companies Thyssen-Klönne MAN Gustavsburg plant Mannesmannröhren-Werke in a joint research project.

P 20 - Steel as a permanent safety element in the construction of cut-and-cover tunnels The starting point for the considerations that led to the award of this research contract was the fact that iron and steel structures have long been used as a permanent support element for tunnelling by mining methods. In contrast, reinforced concrete has been used almost exclusively for open tunnelling. Technically satisfactory solutions are known from special proposals, which are also competitive with reinforced concrete in terms of cost. The fact that such offers were not realised is certainly also due to the following reasons: - Steel for open tunnelling can only refer to a few application examples, - Regulations, guidelines and recommendations hardly address the possibilities of steel, the tendering and awarding authorities only think in terms of concrete, and there are also objections with regard to corrosion, noise and fire, - Regulations, guidelines and recommendations hardly address the possibilities of steel, the tendering and awarding authorities only think in terms of concrete, and objections can also be found here with regard to corrosion, noise and fire, - Civil engineering projects are mostly typical projects of the construction industry, which thinks almost exclusively in concrete, - Steel construction companies are less willing to accept the conditions and risks associated with awarding contracts and contractual practices. There are certainly a number of other more or less concrete reasons. The task of the research contract was therefore to investigate the fundamental possibilities of using steel as a permanent safety element in the construction of tunnels using the cut-and-cover method. This work was supervised by a working group of the Studiengesellschaft für Anwendungstechnik von Eisen und Stahl e.V. (Society for the Study of Application Technology of Iron and Steel).
