By the day the 2014 State Garden Show begins, the construction of a building with a spectacular façade will be completed in the German town of Schwäbisch Gmünd. The project of the local association for noble metals is supposed to emphasize the reputation of the gold and silver town.

Model
The following data refers to the facade construction.
Length: ~ 25 m | Width: ~ 25 m | Height: ~ 25 m | Weight: ~ 55 t
Number of Nodes: 811 | Members: 1,276 | Materials: 2 | Cross-Sections: 7
The house is intended to be used as a place for presentations and events which are associated with matters of gold and silver as well as design.
The design of the building was commissioned by the German planning office isin architekten after winning the design competition. The German engineering office Klöckner carried out the structural calculation of the façade's supporting structure by using RSTAB. For the facade cassettes they used RFEM. In connection with a wind report created by the German I.F.I. Institute for Industrial Aerodynamics, the wind loads to be applied were determined with a model put in a wind tunnel.
Façade Structure
The facade envelopes the building like a coat made of gold leaf. But in reality, the approximately 800 facade plates of 1.5 m x 1.5 m consist of an aluminum alloy that is coated on both sides with DURAFLON®, a FEVE stoveenamel finish for façades.
The steel supporting structure of the facade consists of 1,276 members altogether with steel grades of S 235 and S 355. It is fixed to the building at 80 points. Ten round pipe columns of d=159 mm bear the majority of the vertical loads.
The RSTAB add-on module STEEL EC3 was used for the calculation. The facade cassettes with a thickness of 3 mm were calculated by using the RFEM modules RF‑IMP, RF‑STABILITY and RF‑STEEL Surfaces.
The cassettes are stiffened in the field by aluminum edge profiles. These were designed in RF ‑ ALUMINUM.

Wind Flow on Laterally Open Structures According to DIN 1055-4
Since wind on laterally open structures is not addressed in the Eurocode, the 4 cases of the German DIN 1055 Part 4 are referenced.
SHAPE-THIN determines the effective cross-sections according to EN 1993-1-3 and EN 1993-1-5 for cold-formed sections. You can optionally check the geometric conditions for the applicability of the standard specified in EN 1993‑1‑3, Section 5.2.
The effects of local plate buckling are considered according to the method of reduced widths and the possible buckling of stiffeners (instability) is considered for stiffened sections according to EN 1993-1-3, Section 5.5.
As an option, you can perform an iterative calculation to optimize the effective cross-section.
You can display the effective cross-sections graphically.

- When calculating a cable using the STEEL EC3 add‑on module, there is the error message "Incorrect characteristic stresses for material No. 1! Please correct this in Table 1.2."
- Are effective length factors determined automatically from a model in the add-on modules for the aluminum and steel design or do I have to make adjustments?
- I design a cross-section created in the SHAPE‑THIN program by using the RF‑STEEL EC3 add-on module, but the program shows the error message "ER006 Invalid type of c/t-part for cross-section of type General." What can I do?
-
Is it possible to calculate with American steel cross-sections?
- Where do I find the setting to specify the entered structural component as a "wall" or "slab"?
- How can I quickly model a chimney with reinforcement rings and stiffeners?
- How can I model and design general bolted connections with the surface and solid elements in RFEM?
- I get the message "Existing torsion -> no stability design possible." Why does this appear and what can I do?
- I design an asymmetric cross-section and get the message: "Non-designable: ER051) Moment about z‑axis on asymmetric cross-section, taper or set of members." Why?
- How can I consider holes in steel members?
