The model connecting to the bridge chamber was designed as part of the steel launch nose project for highway D35 in the Czech Republic. This steel launching cantilever allows for future dimensional variations, such as shortening the nose. The structure is adapted for connection to the concrete cross-section by prestressing rods. For a more detailed analysis of the structure, a spatial shell-beam model was created in the RFEM program. The authors of the computational model are Ing. Petr Nečesal, Ing. David Marván, PIS PECHAL, s.r.o.
