Annotation: It was considered the different cases of self-supported chimney calculated scheme modelling, that is stalky scheme in the form of the cantilever bar of uniform cross section; calculated scheme in the form of structural shell, modelled in the ANSYS Workbench 14.0 software solution; calculated scheme in the form of structural shell factored in substructure modelled in the ANSYS Workbench 14.0 software solution; calculated scheme in the form of unstructural cylindrical shell with geometrical deviation in the form of dimple. The received values of equivalent strain (von Mises’s strain – σeq) were compared with the main strains (σx), defined analytically for cantilever shell with equivalent strains (σeq) in the scheme with dimple for the structural shell in the ANSYS. The comparing approved the 15 % deviation strains for structural shell’s and the 65 % deviation fort the shell with dimple.
Keywords: chimney, calculated scheme, dimple, numerical methods, ground, equivalent tension, local tension, cylindrical shell.
