    Abstract. The results of the test of a building structure made of technical coated fabric with an asymmetric uniformly distributed load located on half of the structure are considered. The aim of the study was to verify the scientific hypothesis that the account of shear stiffness makes it possible to fully and reliably determine the stress-strain state and predict the behavior of building structures made of technical coated fabrics. In the course of the work, the approbation of the adequate use of a non-linear orthotropic model of behavior of technical coated fabrics under loading, an orthotropic elastic-plastic model by the Hill's yield criterion, in numerical calculations in the program ANSYS was performed. A numerical study imitating the test of the structure in the PC "ANSYS" was conducted. A comparison of these numerical calculations and results of structure testing shows the possibility of using a linear and nonlinear orthotropic model of the behavior of a material under load in numerical calculations of similar structures. When analyzing the results of numerical experiments, it is established that shear stresses make a significant contribution to the stress-strain state of building structures made of technical coated fabrics.
    Key words: building structures made of technical coated fabrics, experiment, numerical study, orthotropic shells, ANSYS.
