Tensioned Cladding Elements for Cable Roofs

By Dmitrijs Serdjuks, Kārlis Rocēns and Raimonds Ozoliņš

Abstract

Pneumatic cladding element for the long span cable roofs was considered. The pneumatic cladding element is formed by the generally woven by the basket weave fabric from the Vectra (LCP) yarns, which is covered by the PoliTetraFluoroEthylene (PTFE) copolymer foil, and compliant contour, consisting from the several glued together layers of the mentioned covered fabric. The design procedure of the pneumatic cladding element was developed. The dependences of the materials consumption of the pneumatic cladding element on the internal pressure of the air and relations of maximum deflection of the surface of pneumatic cladding element to it dimension are obtained. It was shown, that the using of pneumatic cladding element instead of rigid ones, enables to decrease energy consumption on the transportation and assembling more than four times
