Forum Gold and Silver in Schwäbisch Gmünd, Germany
Customer Project
By the day the 2014 State Garden Show begins, the construction of a building with a spectacular facade will be complete 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 refer to the facade construction.
Length: ~ 82 ft | Width: ~ 82 ft | Height: ~ 82 ft | Weight: ~ 61 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 facade's supporting structure using RSTAB. They used RFEM for the facade cassettes. 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.
Facade Structure
The facade envelops the building like a coat made of gold leaf. But in reality, the approximately 800 facade plates of 4.9 ft x 4.9 ft consist of an aluminum alloy that is coated on both sides with DURAFLON®, a FEVE stove enamel finish for facades.
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=6.2 inches 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 0.11 inches were calculated 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.

- The load distribution on my members looks different when using the Load Transfer surface vs. the Load Wizards. What is the reason?
- I received an error message “Surface of incompatible type... (Surface in upper plane of building story must be of ‘Load transfer’ type)” when running the calculation. What is the reason?
- My beam has a continuous lateral support and therefore lateral torsional buckling (LTB) is not a concern. How do I define the effective length?
- How can I efficiently define line hinges on several surfaces?
- How do I include the overstrength factor(s) Ωo in the ASCE 7 load combinations?
- How do I include the overstrength factor(s), Ωo in the ASCE 7 load combinations?
- How do I include the redundancy factor(s) ρ in the ASCE 7 load combinations?
- My live load is less than or equal to 100 psf. How do I consider the reduced load factor in the ASCE 7 load combinations?
- I do not see the seismic load cases in my generated ASCE 7 load combinations (COs). How do I add them?
- How do I create an imperfection based on a mode shape in RFEM 6?
