Porr Projekt und Hochbau AG
Kematen in Tirol, Austria
The fourteen-storey hotel is directly facing Olympiaworld, Tyrol's largest sports and event center. The building represents one of the highest constructions of the beautiful Alpine city.
Entering the terrace on the eleventh floor, visitors enjoy a breathtaking panorama of the Tyrolean mountains and the Bergiselschanze, a world-famous ski jumping hill which is part of the annual International Four Hills Tournament.
The customer of Dlubal Software, the engineering office in.ge.na was in charge of the testing work. Test engineers used RFEM to enter the 3D model including loads and to calculate the structure.
The construction object is a new building representing a fourteen‑storey hotel with a cellar. It was built as solid construction consisting of reinforced concrete. The inclined external walls in the east and west have a slope of 73.2° in relation to the building's horizontal.
The horizontal as well as the vertical loading is transferred by the columns and wall surfaces of the central corridor respectively the external walls. The external wall surfaces in the areas of the north and south facade have a thickness of 20-25 cm. The inclined walls in the west and east have the same thickness of 20-25 cm depending on the loading.
The floor thickness in the uncovered zone of the underground parking is 35 cm, in the zone with superstructure it is 30 cm. The ceiling above the twelfth floor is 30 cm thick. All other intermediate floors were built as standard floor ceilings with a thickness of 25 cm.
The foundation below the covered area of the building was constructed using flat footings with thicknesses of 1.00 m, 0.60 m and 0.30 m. Zones without superstructure were built up on strip and single foundations. As a result of calculations, lifting forces were determined in the western part of the building structure for the extraordinary action of earthquakes. To ensure stability in the described area, GEWI anchors were arranged.
