Objectives and Work Programme
In the building industry, opaque components are increasingly replaced by glass elements. Due to the brittle material behaviour, a direct transfer of standard connection methods, such as screw connections, to glass elements is not possible. Especially, the realisation of hinged connections is a great challenge for the planners. Usually, hinged connections of load-bearing glass elements are made by unsing single bolts. In the hole area of the glass, this leads to high, often design-leading stress concentrations. As a result, the glass elements are inevitably oversized or have an increased risk of breakage.
The novel flexAGt mounting system is based on an innovative three-part joint construction and enables a rotation of the glass elements without drilling. The glass element is long-term connected to a filigree gliding shoe via form closure and non-positive connection. The glass cross section can thus be used in full for load transfer in the connection area while avoiding critical stress concentrations. This results in significantly lower stresses in the planned hinged mounting system compared to systems with bolt connections. A specially developed test method is used for experimental studies of the system and to prove the force transmission level. The required gliding properties with high abrasion resistance are verified in experimental tests. Numerical simulations accompany the experimental work in the project.
The aim of the project is to develop a material-conform mounting system for glass elements to realise hinged connections using the full glass cross-section. This novel mounting system can be used for load-bearing glass fins and glass beams.
