Glass frame corners: Transparently bonded glass frame corners

Objectives and work programme

This project investigates transparently bonded, load-bearing, all-glass frame corners. The first step is to identify the requirements of the frame edges for use in glass construction and to conduct research on the adhesive bonding systems that may be used. Preliminary studies on numerous substance samples form the basis for determining the material properties of the adhesive. In order to select suitable adhesives for use in the components, the strength of small-scale samples is tested under varying framework conditions (temperature, humidity, UV radiation, ageing). These results are used to develop and calibrate digital prototypes for use in numerical simulation. Using the verified and validated calculation model, the stress distribution in the bonded joint and in the glass is determined. Numerical calculations and experimental explanations are conducted in parallel in order to optimise the geometry, load-bearing capacity, long-term durability and longevity of the all-glass frame corners. The objective is to achieve a glass corner with a completely transparent appearance, a concept that has inspired architects since the Classic Modern Era. Thereafter, the approval basis for use in construction will be established for this construction technique, which is yet to be standardised.

The research project is funded by the Federal Ministry of Economics and Technology (BMWi) as part of the Central Innovation Program for Mid-Sized Businesses (ZIM) and conducted in collaboration with First Glas GmbH of Berlin and GSK (Glas Statik Konstruktion GmbH, Dresden office).
