Curved glass panels have a particular appeal in contemporary architecture, but they are often costly and/or relatively heavy elements.
This paper describes the engineering design and assembly of an FRP-glass vision panel that is easy to construct, lightweight and can be easily adjusted to a broad range of single and double curvatures.
The paper describes the salient challenges in the design and construction of a prototype panel made of thin glass, fibre-reinforced polymer pultrusions and structural adhesives, in particular: (i) the numerical modelling of the cold bending process to avoid undesirable cold-bending distortions and snap-through buckling; (ii) the design of novel articulated corner joints that can accommodate and retain a broad range of panel curvatures and (iii) the fabrication process of a lab-scale prototype panel, including the cold bending of the panel.
The paper demonstrates that it is possible to design and construct such a panel and identifies the other engineering challenges that need to be addressed in order to advance this working prototype from its current stage of development to a real-world product.
