Mountain Station/Garaging Hall Zinsbergbahn, Brixen im Thale, Austria
The "Zinsbergbahn" project was certainly anything but standard and therefore, the Grabner Stahlbau team had to solve many unresolved challenges.

At Grabner, experts in structural analysis, engineering, production, logistics, and assembly got down to work in order to implement this project in the best possible way.
Construction and Assembly
In all project phases, the architecturally appealing garaging hall, which is a cantilevered structure of about 98 ft and supported by 3 columns only, has been a real challenge. The long cantilever combined with high wind loads, in connection with the maximum deformation limits allowed by the equipment manufacturer, have been the greatest challenges to be solved.
From a technical point of view, using large welded trusses would have been easier, but they would not have been suitable for transport and assembly. Therefore, the Grabner Stahlbau team has decided to develop individual structural components being appropriate for assembly and all phases of the transport, but still meeting the structural demands with regard to deformation.
Concerning production, these requirements resulted in very demanding tolerance limits, in a special assembly concept including additional columns, and in some specifically created bases for platforms in the steep ground. Those were positioned by walking excavators and cranes so that the structural components could be installed safely and on time, 98 feet above the ground.

- How do I apply wind load on members of open structures?
- I do not want to design a cross-section in the RF‑/STEEL EC3 add-on module. Can I quickly remove this cross-section from the selection?
- I have a roof structure resting on a steel column that runs to the foundations. The column runs through a perimeter wall that supports the false ceiling. A considerable part of the load from the roof is transferred to the wall. I want the steel column to carry all the vertical loads from the roof. How can I do it?
- Are the models and presentations from Info Day 2018 freely available, and can you send them to me?
- How can I display membrane stresses in the results of RF‑STEEL Surfaces?
- What is the meaning of the superposition according to the CQC rule in a dynamic analysis??
- How can I display the internal forces in the global coordinate system and not in the principal coordinate system of the cross-section?
- I am designing a set of members using the equivalent member method in RF‑/STEEL EC3, but the calculation fails. The system is unstable, delivering the message "Non-designable - ER055) Zero value of the critical moment on the segment".What could be the reason?
- I want to create a mapped mesh for a circular hole plate. Is it possible to generate such a mesh in RFEM?
- I have a trapezoidal roof structure supported by beams. However, the moments on the beams are smaller than they should be. What could be the reason for this?
