Researches of the stress-strain state unit of connection of walls with the bottom in vertical cylindrical tanks in volume 10 000-50 000 m3
Abstract: The question of justification of the finite element calculation scheme the node pair with the bottom wall of the vertical cylindrical tank of large volume (10 000…50 000 m3). Main factors influencing the stress-strain state of such sites (geometric and stiffness parameters, design solutions, the strength characteristics of the material, interaction with the ground, uneven cake, etc.). On the basis of numerical studies are summarized obtained regularities of changes in key parameters of the stress-strain state (radial and circumferential strain, radial displacement) of the above-mentioned factors of influence. Proposed analytical expressions to describe the set of patterns that can be used in the design and the refinement of the stress-strain state of the walls of the reservoir is operated in the area unit of connection of walls with the bottom.
Keywords: tank with one wall, connection of walls with the bottom, stress-strain state, the local effect, numerical analyses.
