The study of an inelastic properties of the technical fabric Valmex used for 20 years as the roof structure of the Forest Opera in Sopot (Poland) is presented. The uniaxial tensile laboratory tests with constant strain rate have been conducted and analysed. Parameters of the Bodner-Partom constitutive model have been identified and verified by numerical simulations. Two approaches of the parameters identification have been proposed: one (simplified) for laboratory analysis and the other (extended) for numerical calculations of the shell structures covered with the technical fabrics. Both approaches have proved their correctness in the FEM analysis.
