Prestressed cladding element for cable roof
Prestressed cladding element for cable roof Prestressed cladding element for the long span saddle-shaped cable roofs was considered. Peculiarity of the cladding element is absence of rigid contour. The load bearing cables of the roof supports prestressed cladding element. The generally woven by the basket weave fabric from the Vectra (LCP) yarns, which is covered by the PoliTetraFluoroEthylene (PTFE) copolymer foil, steel cables and steel pipes were considered as the materials of covered fabric, load-bearing cables and central pillar, correspondingly.The covered fabric is joined directly with the cables of saddle-shaped roof and the displacements of the cables have significant influence on the prestressing level of cladding element. Influence of the displacements of 50×50 m cable net of saddle-shaped roof on the prestressing level of cladding element was evaluated. The design loads combination includes dead weight, accidental snow load and prestressing. It was shown, that the maximum vertical displacements of prestressed cladding element changes within the limits from 34.80 to 43.27 mm, when the level of prestressing for tensioned fabric and heights of prestressed cladding element changes within the limits from 0.2 to 0.6 from it load bearing capacity and from 0.25 to 1.00 m, correspondingly.
