COMBRI, a research project for designing bridges of the future

May 20, 2009

The TECNALIA Technological Corporation have taken part, through its Construction Unit, in the European research project, "Competitive steel and composite bridges by innovative steel plated structures - COMBRI", the goal of which is to make advances in design for the bridges of the future.

The COMBRI research project and the dissemination project "Valorisation of Knowledge for Competitive Steel and Composite Bridges - COMBRI", the latter being an adjunct of the former, have come together to issue the COMBRI Design Manual in order to improve the competitiveness of steel and steel and concrete composite bridges through helping to implement the most recent methodologies in structural design in the European Union using Eurocodes. Both projects are financed by the European Commission's Research Fund for Coal and Steel programme.

The COMBRI project has focused specially on the verifications of the plate buckling of steel plated structures and, thereby, on the contents of the following Eurocodes: EN 1993-1-5 "Plated structural elements", EN 1993-2 "Steel bridges" and EN 1994-2 "Composite bridges".

The COMBRI Design Manual is divided into two parts, to provide a more clearly organised document for its practical application:The most outstanding results of COMBRI are the following:Finally, within COMBRI it has been developed the software EBPlate to determine the elastic critical buckling stresses for their application in the design of bridges.

Apart from TECNALIA Construcción, the COMBRI consortium is made up of: Universität Stuttgart, Institute for Structural Design / Institut für Konstruktion und Entwurf (KE), RWTH Aachen University, Institute for Steel Structures, Centre Technique Industriel de la Construction Métallique (CTICM), Luleå University of Technology, Division of Steel Structures (LTU), Université de Liège, ArGEnCo Département, Services d'Études Techniques des Routes et Autoroutes (SÉTRA).
