Review article

There has been carried out analytical and numerical study of the work of axisymmetric thick truncated cone shaped plates under the action of uniformly distributed load. Using the known criteria for concrete strength and accepted assumptions in the analytical calculation method, and also on the basis of the numerical software complex ANSYS Workbench, calculations were made with the purpose of determining the extreme pressure value and the stressed state, taking into account the key type conjugation of the thick plate with the load-bearing wall of the high-pressure shell, meanwhile observing the dependencies on variable rigidity, which may be high enough in one case and weak in another case. A comparative analysis of the calculation results is presented that shows the adequacy of the proposed calculation methods.
