Description

The exterior design and shape of a building is determined beside by architectural demands increasingly by technical criteria as the transparency and filigree of the construction, the requirements regarding building physics and the energetically and sustainable performance. The complexity in design, planning and production increases especially in the case of building envelopes.
The demand for a maximum possible transparency of the faade structure in combination with the increase in complexity due to geometry and due to the requirements of energetically and ecological optimization requires a consequent design under the presumption of the maximal and functional integral utilization of all the involved structural building elements. For this reason an important aspect when designing challenging building envelopes is the constructive development with regard to an optimal assembling and an optimized structural behaviour, where the properties of the used building elements and materials are exploited at their best.

In this research project technical approaches are worked out to positively support this developments and to contribute to an optimization of the structural behaviour and to the energetically and ecological sustainability.

The aim of the research project is to develop steel-glass-structures with a hybrid structural behaviour for the building envelope. These structures should on the one hand increase the transparency and on the other reduce the material consumption and the assembly effort. To achieve this goal the research team of the Institute of Building Construction from the Graz University of Technology, with the involvement of the Laboratory for Structural Engineering and the Know-How of the Waagner-Biro Stahlbau AG, will perform studies of the actions and requirements of glass building skins, analysis for the load transfer into the glass sheet in- and out-of-plane, for the structural behaviour of the glass sheet in a single element and for the influence of the stiffness of the steel construction on the structural behaviour, investigations for the force-fitted connection of the individual components, for the constructive development of the resulting hybrid structures and for the structural behaviour of the complete system.

The methodology for achieving the aimed goals includes theoretical, engineer-like analysis, numerical studies, experimental investigations, their comparative evaluation with final conclusions and the suggestion of a design concept.
