Oberholz Alpine Hut, Italy
Customer Project
At a height of around 6,889 ft you can enjoy a breathtaking view of the Dolomites with a delicious meal. Since 2016 these amenities have been available at the top station of the Obereggen skiing area, South Tyrol. The Oberholz alpine hut restaurant, with its exceptional architecture, fits perfectly into the surrounding landscape.

Structural Design |
Bauingenieure Hartmann & Gamper Dr. Ing. Andreas Erlacher www.ing-erlacher.com |
Engineers Daniel Hartmann and Andreas Erlacher performed the structural analysis on a 3D model in RFEM. The company LignoAlp from Brixen was in charge of the design and execution of the whole timber structure.
Structure
The structure lies partially below ground level and, protruding from the earth, looks like a tree trunk from above. The ends of the three subtly designed ridge lines are oriented towards individual mountain chains. At these ends, there are large pentagonal panoramic windows that offer a perfect view from the restaurant.
The structure consists of wooden portals, visible from inside and making up the spatial curved structure. The intermediate area, which is variable in size and distance, has been coated with wooden panels. Each portal consists of three chambers and has a width of 8.2 ft in total.
The whole exterior facade, including the roof, has been coated with larch wood slats, the supporting structure and the interior paneling with spruce wood.
With the Oberholz alpine hut, the planners and executors have succeeded in accomplishing peak architectural performance. Furthermore, the alpine hut has excellent ecological balance with its use of timber.

Saving Models as Blocks in RFEM 6
In RFEM 6 it is possible to save selected objects, as well as whole structures, as blocks and reuse them in other models. Three types of blocks can be distinguished: non-parameterized, parameterized, and dynamic blocks (via JavaScript). This article will focus on the first block type (non-parameterized).

Timber Design | Strength and Stability | Input
The structural system is entered and the internal forces are calculated in the programs RFEM and RSTAB. The program provides access to the extensive material and cross-section libraries.
Timber Design is completely integrated into the main programs and automatically takes into account the structure and the available calculation results. Further entries for the timber design, such as effective lengths, cross-section reductions, or design parameters, are assigned to the objects to be designed. It is possible to select the elements graphically by using the [Select] function.
