[more ▼] Due to the demand for sustainable buildings and slim constructions, composite slim-floor systems become more important. The present European Codes do not include complete de-sign rules for shallow-floor beams. Therefore, the objective of the recent research work was concentrated on the development of additional regulations, considering ultimate limit state, serviceability limit state and fire design.

Seit einigen Jahren sind die Eurocodes bereits in der Anwendung. Basierend auf diesen Erfahrungen und vielfachen Kommentaren aus der Industrie erfolgt derzeit eine Überarbeitung aller Teile des Eurocodes mit dem Ziel, die aktuellen Bemessungsnormen an den Stand der Technik und Forschung anzupassen, die Anwendung zu vereinfachen sowie die Eurocodes untereinander zu harmonisieren. Abschließend werden diese Modifikationen in die zweite Generation der europäischen Normen überführt. In den folgenden Ausführungen wird die Arbeit des Projekt-Teams SC4.T1 vorgestellt.

[more ▼] As part of the development of the second generation of Eurocodes and harmonization of the different European Codes, some clarifications deal with the design value of concrete compression strength and the bending design of steel-composite sections. The following background document describes the issues in design and confusions between Eurocode 2 for the design of concrete structures and Eurocode 4 for the design of composite structures in steel and concrete. The first part is concentrated on the background information and the accentuation of limits for plastic bending design. While the second part represents the results of multiple comparisons between plastic and strain limited design leading to a new design approach.

Thereby the ambitious specifications of the investor as well as the requirements of the local authorities could be met only through a comprehensive and intelligent planning process. The complex interrelation between logistics and construction management processes, detailing and overall economic assessment found the solution of steel-composite design highly performant and efficient in every aspect.

Parallel to the traditional sections consisting of rolled profiles with an additional bottom plate also floor-slabs with integrated steel-box sections have gained widespread adoption in practice in the recent years. Because of the sheathing of the concrete by the steel section a hybrid truss model with a compression strut in the concrete section is developed, increasing the shear resistance of these sections. Due to the additional steel stresses resulting by the truss model, the relationship for the interaction between moment and vertical shear forces is to expand.

[more ▼] Transport policy in Luxembourg provides the realization of a dense network of public transport. Motorists, especially the large number of commuters from the neighbor countries, should already change close to the borders to public traffic – especially to train. By that it is possible to relieve the national highways and also those in bordering regions. With the start into service of the new multi-storey car park Belval-Université in 2013, the first of a series of planned Park & Rail projects is realized. It is the most modern car park in Luxembourg and complies with high standards in architecture and traffic management systems. Together with the immediately adjacent train station, an intermodal platform with excellent transport links to the international financial center of Luxembourg City is created.
