Design of fixed points of standing seam profiles on decking profiles. Roof thrust from the outer layer of a double-layer roof structures has to be introduced into the inner layer. Usually this is done at fixed points at the roof ridge. An outer layer of standing seam profiles attached to crests of the inner layer of trapezoidal sheeting at discrete points is a typical example. In this case, additional transverse bending moments occur. They sheeting panels are loaded with a line load transversely to the direction of span. Within the scope of a research program, investigations on the load-bearing capacity and deformation behavior of the sheeting panels of the inner layer were performed. The work resulted in the design and calculation approaches presented here. © 2013 Ernst & Sohn Verlag für Architektur und technische Wissenschaften GmbH & Co. KG, Berlin.

Twinskin roof structures are typical in lightweight metal construction because of the flexibility they offer in the combination different components. This allows unusual demands on the design or strict requirements for fire, acoustic and lightning protection to be met. To combat material-related heat loss or thermal bridging through metal parts, there are well established solutions provided by the use of alternative materials without any loss of quality or performance. Using the example of demanding requirements on the shape and size of the roof for a new sports arena for the 2014 Winter Olympics in Sochi, the performance capability of a twin-skin structure with profiled metal deck lining and an outer skin of industrially manufactured of aluminium standing seam profiles is shown. © Ernst & Sohn Verlag für Architektur und technische Wissenschaften GmbH & Co.
