HybridGlasSt: Product development of hybrid steel-glass composite girders

Objectives and work programme

The use of glass as a load-bearing component in facade structures requires special solutions to be developed due to the absence of technical structural specifications for planning and construction. Previous applications of these kinds of linear glass elements have involved rectangular, laminated glass panes. As a result of the brittleness of the material, the technical requirements for the joining process and the issue of low redundancy in such components, no adequate solution has been found to date. Therefore, developing hybrid glass-steel composite girders should contribute to creating an innovative solution by combining glass and steel in a way that is suitable for this application.

Linear adhesive bonding is seen as a suitable joining method for the materials in the hybrid steel-glass composite girders. The resulting cross-section shapes allow for an increased load-bearing capacity compared with rectangular glass supports, due to the high level of geometric rigidity. Additionally, the required redundancy of the components can be improved by strengthening the brittle glass with ductile steel. Components made of steel also allow for the use of conventional joining techniques for connecting additional components or for joining the components with one another.
