Prestressed cladding element for the long span saddle-shaped cable roofs was considered. Peculiarity of the prestressed cladding element is absence of rigid contour. 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 50x50 m cable net of saddle-shaped roof on the prestressing level of cladding element was evaluated.
