As part of the Porsche exhibition 2012 in the Linz tobacco factory, an impressive grandstand construction was designed and structurally implemented as part of a complex exhibition area. The combination of sophisticated architecture, multifunctional use and aesthetics design placed special demands on the structural design.
Design features of the grandstand
The grandstand is an elevated structure that serves both as seating area and as an exhibition space underneath the structure. It is accessed from the side via an accessible ramp, while the entire structure is surrounded by a textile covering that gives the grandstand its striking geometric shape.
Primary structure
- The timber supporting structure of the grandstand is based on three main trusses, which are stabilized in the central area by V-shaped supports.
- In the rear area, additional individual supports provide the connection to the existing reinforced concrete supports of the building.
- Horizontal bracing is provided at grandstand level by steel tension rods between the main girders. Alternatively, timber cross-sections were also used to integrate the structure visually and functionally.
Side Ramp
- The access ramp is designed as an independent, elevated structure with transverse and longitudinal bracing.
- Plywood panels are used as planking, with the direction of tensioning of the panels (transverse or longitudinal) influencing the dimensions and loadbearing capacity.
- The last ramp section is not elevated independently but is connected directly to the grandstand via a cantilevered beam.
Enclosure of the construction
The grandstand is surrounded by a textile covering that is supported by a truss structure. The inclined outer surfaces and the cantilevered corner above the entrance to the exhibition space required precise structural calculations to take account of deformations and vibrations. The envelope is suspended from the extended main trusses of the grandstand in order to effectively transfer the loads.
Special challenges
- Geometric complexity: The inclined outer edges and the cantilevered access required precise planning of the load transfer and deformation control.
- Multifunctionality: The grandstand combines several areas of use, from seating areas and ramps to exhibition rooms, which placed different demands on the supporting structure.
- Combination of materials: By combining timber and steel elements, a harmonious design was achieved in addition to structural stability.
The static calculation and execution of the grandstand illustrates the synergy between artistic design and engineering. The construction combines stability, functionality and aesthetics and thus contributes significantly to the overall experience of the exhibition.
The KPPK team has made the seemingly impossible possible — and with brilliant quality! Thank you very much for the excellent collaboration.
