Innovative steel-glass components for high-performance building skins: testing of full-scale prototypes
Abstract High-innovation of products is a worldwide key-competitive factor. The most important technological achievements in modern architecture are attained by constructing smart building skins, usually by combining glass and metal. The European Research Fund for Coal and Steel (RFCS) project “S+G” (Steel+Glass) studies steel-glass composite systems for high-performance skins using adhesive junctions meeting requirements of as well energetic, technical and aesthetical disciplines. Within the research project cold-formed glass elements with a hyperbolic paraboloid shape were developed, where glass is structurally bonded with a metal frame. One of the focuses of the project was on full-scale tests on three different kind of prototypes, which have been performed to study the steel-glass composite system with various adhesives under different loading. Indication of several applicable adhesives for the steel-glass junction were provided. Among the products available on the market, three different-in-type materials were considered: High performance structural silicone, polyurethane-based adhesive and an innovative silicone structural adhesive. The strength and stiffness of single cold-formed cells under out-of-plane loading with regard to loads acting perpendicular to the surface were assessed, especially regarding the action on bent glass, the long-term behaviour and the residual resistance after breaking of one or all glass panes of a laminated glass. The capability of glass to prevent buckling of slender steel members was a crucial issue to consider. This paper presents the main experimental results of full-scale tests regarding out-of-plane loading and first results of numerical investigations. The results demonstrate the possibility of using the structural bonded steel-bent glass composite structures as a facade element in modern architectural design.
