Research of the Stress-Strain State of Vertical Cylindrical Steel Tanks for Storage of Oil and Oil Products

The purpose of work conclude with determination of solid characteristics and stability of plumb cylindrical reservoir based on the examination of the stressed deformed state by using method of ultimate components. 3D model was created in the module APM structure 3D CAD - system and carried out the stressed deformed state research of the plumb cylindrical reservoir for saving liquids. Design of durability and stability of metal construction was accomplished by means of an external force and proper gravity (weight) of the metal construction. An important role at the solution of tasks of the linear theory of stability is played by a method of final elements, so as this method gives opportunity to consider the irregularities of loading and geometry of a design which aren't giving in to the account in classical methods. Proceeding from the received results, it is recommended to carry out when carrying out technical survey of the tank calculation by method of final elements with the purpose of identification of zones with the maximum concentration of tension and detection of defects of metal.
