Abstract: Fibre linear tensile elements 2 are strung between the floor slab 11 and the roof 12 of a building 1. Each fibre linear tensile element has a structural core 21 of polymeric fibres or filaments which can accommodate the tensioning of the fibre linear tensile element. The core 21 is covered by a sheath 22 of polymeric material. The fibre linear tensile elements 2 carry clamping devices 3 which enable glass panels 4 to be secured in position. Each clamping device 3 clamps in position the corners of four adjacent panels 4 at a particular connection node of the glass wall 80, as shown in FIG. 6. Gaskets 78 are applied to fill the inter-panel joints. Each fibre linear tensile element 2 may include a central optical fibre 23 for detecting any reduction in the tension during use. The tension of the fibre linear tensile elements 2 is monitored by a monitoring device 81 which can produce an appropriate alarm signal.
