[BIM Software Implementation Case Study] Rappenloch Bridge

Introduction of a case where the assembly and disassembly of support scaffolding using a slightly inclined arch-shaped steel pipe truss was adopted!

The new Lappenloch Bridge is a single-track prestressed concrete bridge, with a total length of 66 meters for the superstructure. Since the Durnbiller Aach River flows beneath the bridge, it was necessary to use free-span formwork for construction, and a seating area was provided under the abutments. Additionally, due to the very narrow surrounding roads and limited access, the development of a lightweight formwork system was required. The maximum weight of each component at the top of the arch is limited to about 4 tons, and the total length of components that can be transported via existing roads is up to 12 meters. To address these stringent challenges, a slightly inclined arch-shaped steel pipe truss was adopted. This lattice truss is connected to the cross members to enhance load-bearing performance and is reinforced with tie rods to ensure the static load-bearing capacity of the concrete. All process planning from assembly to dismantling was carried out using "Tekla Structures." *For more details, please feel free to contact us. ⇩ The catalog can be downloaded from the special website below ⇩
