Analysis of Numerical and Analytical Values of the Tank Wall Stability Factor
Abstract: The change in the stress state and the wall stability coefficient of the vertical cylindrical tank shell is studied when horizontal stiffening rings are placed according to the norms of the European Union and the Russian Federation. The main load is wind, taking into account the real flow distribution. The aim of the study is to obtain an adequate finite element model for further study of the influence of the stiffening rings on the stability of the reservoir wall. Analytical values of the safety factor of stability are determined by the methods given in the normative documents of the European Union and the Russian Federation. Numerical values of the resulting stresses and stability factors are determined by the finite element method. For this purpose, the LIRA-CAD 2015 R4 computational complex is used. As a result, the effect of using the stiffening rings on the magnitude of the critical and acting stresses was determined. Also, the numerical and analytical values of the stability factors for the stability of the stiffening rings are determined.
