    Abstract. The actual problem of calculating for seismic effects, which consists in the existence of a contradiction between the linear elastic models of materials used, as well as the linear spectral method of calculation and the essentially non-linear nature of the deformation of the bearing systems of buildings and structures, is considered. This problem can be solved using a direct nonlinear dynamic method and verification with identification of design parameters for models of materials, individual bearing elements and for systems consisting of individual elements. The results of a comparative analysis of experimental and numerical studies are presented, the patterns of destruction of samples, as well as the isofields of the intensity of plastic deformations are given. It is concluded that the controlled parameters, damages and crack formation sites are in good agreement.
    Keywords: linear-spectral method, non-linear dynamic method, non-linear concrete model, damage accumulation, verification of the design model, seismic resistance of the building
