Rational design solutions of ensuring the walls of tanks stability to the action of transverse loads

Abstract

Abstract The article considers the task of an integrated approach to the study of the rationality of strengthening the cylindrical walls of large volume tanks with stiffening rings under transverse loads. Based on the results of computational studies, the principles of placement and rational boundaries usage of stiffening rings for vertical cylindrical tanks of various volumes are determined. The results were obtained for ideal shells and for cases of the presence of a typical geometric wall defect in the form of the angularity of a vertical weld. To validity the reliability of the results obtained, an experimental verification of the numerical model was carried out.
