GS&E journal > Conceptual design and FEM structural response of a suspended glass sphere made of reinforced curved polygonal panels

The paper introduces a novel concept for structural glass shells that is based on the mechanical coupling of double curved heat-bent glass panels and a wire frame mesh, which constitutes a grid of unbonded edge-reinforcement. Additionally, this grid has the purpose of providing redundancy. The pane...
