Building and Testing Lenticular Truss Bridge with Glass-Bundle Diagonals and Cast Glass Connections

On the campus of Delft University the Glass and Transparency Research Group is preparing to build a pedestrian bridge as a low arch consisting of dry-stacked glass blocks. As temporary support for the arch, a lens-shaped truss has been constructed and placed on location. This truss has been fitted...
