Abstract
The reuse of large-scale structural glass panels is significantly limited by existing connection systems. The existing connection methods either permanently alter the glass panel or leave residual damage upon disassembly, resulting in the disposal of structurally intact panels. This thesis investigates the feasibility of developing a fully demountable connection system for large-scale structural glass applications that addresses this gap.
The proposed system, uni.conn, introduces a mechanically controlled interlocking connection that meets the required structural performance benchmarks while allowing the connection to be attached, repositioned, and removed without permanently modifying the glass panel. The system consists of three components: a glass module with a modified rebated edge profile, a three-part mechanical insert comprising a pin, link and sleeve, and a gasket that acts as the load-transferring interface between the insert and the glass. The interlocking and separation of the pin and link is controlled by an external magnetic field, enabling disassembly without mechanical intervention at the connection itself. The structural behaviour of the system is investigated through load path analysis and finite element analysis at a product level using ANSYS Workbench.
The results demonstrate that uni.conn enables glass panels to be reused across different structural configurations without being constrained by specific connection locations or damage upon disassembly. While developed at concept level, the findings contribute to the broader effort of improving circular practice in the glass industry.
