The article discusses the development of algorithms and methods for calculating the stress state and strength of thick-walled spherical concrete shells under the influence of uniform external pressure. There have been obtained analytical and numerical solutions of the problem of determining the limiting external pressure using the main principles of the theory of plasticity taken in the form of the Drucker-Prager strength criterion and the ANSYS Workbench software package.
