Abstract: In this paper, we consider the dynamic reaction of an orthotropic cylindrical shell (pipe) in a viscoelastic medium that is subjected to seismic action. The cylindrical shell is infinitely long, therefore, the problem of a plane deformable state is considered. It is assumed that the shell is completely connected to an environment of infinite extent. Only axisymmetric and non-axisymmetric oscillations with an incident compression wave (transverse or shear) were studied. The results were obtained for different characteristics of viscoelastic media - hard, medium and soft. It was found that the orthotropic parameters do not affect the reaction of the cylindrical shell. The degree of influence of orthotropens strongly depends on the degree of rigidity of the environment.

Key words: wave, dynamic reaction, viscoelastic medium, seismic impact, shell.
