Pavilions at Oslo Airport in Gardermoen, Norway
In the new terminal of the international airport Oslo-Gardermoen, five pavilions have been built to provide a space for duty-free shops and restaurants.Blumer-Lehmann AG in cooperation with Lindner Group planned, fabricated and assembled the freely shaped timber structures.

Dimensions of Pavilion M1
Nordic Architects from Oslo, Norway, was responsible for the design, and SJB.Kempter.Fitze provided the structural calculation. A total of approximately 500 Kerto‑Q panels and 1,766 ftm³ of glued laminated timber were used.
The pavilions should originally be made of steel. However, due to the complexity and geometry of the structures, engineers decided to use the timber as a versatile and flexible material.
Form-finding was defined by the architects. This was followed by a refinement of the predetermined surfaces and the development of a supporting structure made of timber ribs (Kerto‑Q beams or glulam trusses). The axis model of the frames was created and transferred to RSTAB. The structural calculation then showed the width of the frames (the height is always constant).
About 10,000 various components were automatically labelled and then fabricated with CNC milling machines. The numbering was determined in such a way that the assembly was nearly possible without a plan.

When designing many members in one design case, it is sometimes difficult to recognize the governing designs. To improve the overview and to display the relevant designs in a compact way, you can use the filter options under the result tables. These are included in all design modules of steel, aluminum and timber structures in RFEM and RSTAB.
- General stress analysis
- Graphical and numerical results of stresses and stress ratios fully integrated in RFEM
- Flexible design with different layer compositions
- High efficiency due to few entries required
- Flexibility due to detailed setting options for calculation basis and extent
- Based on the selected material model and the layers contained, a local overall stiffness matrix of the surface in RFEM is generated. The following material models are available:
- Hybrid (for combinations of material models)
- Option to save frequently used layer structures in a database
- Determination of basic, shear and equivalent stresses
- In addition to the basic stresses, the required stresses according to DIN EN 1995-1-1 and the interaction of those stresses are available as results.
- Stress analysis for structural parts of almost any shape
- Equivalent stresses calculated according to different approaches:
- Shape modification hypothesis (von Mises)
- Maximum shear stress criterion (Tresca)
- Maximum principal stress criterion (Rankine)
- Principal strain criterion (Bach)
- Calculation of transversal shear stresses according to Mindlin, Kirchhoff, or user-defined specifications
- Serviceability limit state design by checking surface displacements
- User-defined specifications of limit deflections
- Possibility to consider layer coupling
- Detailed results of individual stress components and ratios in tables and graphics
- Results of stresses for each layer in the model
- Parts list of designed surfaces
- Possible coupling of layers entirely without shear
- In RF-/TIMBER AWC and RF-/TIMBER CSA, I receive the error that says torsion limit exceeded. How do I bypass this error message?
- Can I consider a reduction of the stiffness according to the German regulation NCI NA.5.9 in TIMBER Pro?
- Why is the strength always reduced by the kmod value of 0.6 during the calculation in the RF‑LAMINATE add‑on module, although I have load combinations with variable loads?
- I have selected all available members for design in RF-/TIMBER Pro. Why are tapered members not designed?
- When performing the fire resistance design with TIMBER Pro, I get the error 10001. How can I fix the error?
- Is it possible to set user-defined values when viewing solid stress results?
- How are the signs for the release results of a line release and line hinges interpreted?
- How can I create a curved or arched section?
- Is it possible to design the support pressure or the compression perpendicular to the grain in RX‑TIMBER?
- After the design with RF‑/TIMBER Pro, I optimized a cross-section. Why is the utilization of the optimized cross-section exceeded now?
