Kurita-Albrecht Best Technical Paper Award - Steel at 12th Japan German Bridge Symposium, September 2018 in Munich
The bridge across the Schorgast Valley is based on a competition-winning design. It comprises an overhead structure consisting of six pylons each with 10 stay cables and a slender composite cross-section with a torsion-resistant steel box as the bridge superstructure.
The jury concluded that the competition submission was a self-assured accomplishment integrating harmoniously into the sensitive landscape of the Schorgast Valley. The substructure solution shows great transparency, emphasizing the significance of the superstructure. All in all, the design is a convincing contribution to the region's building culture characterized by innovative spirit and creative power.
The structural analysis of the cross-girders and the supporting frame structures is explained in this article. To this end, the section forces from the global model were applied to a local finite element model.
