The brittle material behaviour of glass together with the lack of a reliable model to incorporate the effect of internal residual stresses in structural designs pose challenges to structural engineers when designing of load-bearing glass structural members, such as large panels, roofs, floors, staircases and partitions. The current industry practice is to overdesign the glass elements.


This talk will introduce the idea that a hybrid contour method-eigenstrain model can be used to incorporate the effect of residual stress in float glass. The application of the contour method to glass, or to any nonconductive material for that matter, is novel. This is also the first use of waterjet cutting for the contour method. The talk describes the experimental effort made to make a good cut for glass in contour method analysis. In the second half of the talk, the use of glass–GFRP (Glass Fibre Reinforced Polymers) hybrid as a strong and ductile composite is exploited. Using the results of a combined experimental/numerical investigation into the load response and failure behaviour of float glass–GFRP hybrid beams, in which a layer of GFRP bonded between two horizontal glass sheets, it is shown that strong and ductile structural members can be made from float glass.
