VTR® is a registered trademark of SSF Ingenieure AG for a composite girder grid construction method. The substructure consists of longitudinal steel girders onto which industrially fabricated reinforced concrete girders with structural prestress are placed and connected to the longitudinal girders to form a grid. Modularly fabricated slabs as fully or semi prefabricated components (with cast in-situ parts) complete the grid of longitudinal and transversal girders to form a continuous deck.
In the newly published project brochure on the subject of fast construction, the system of this method is explained, its advantages compared to conventional construction are elaborated and current reference projects are presented.
