The current study addresses the high risk of buckling in open-top tanks. The only method of reinforcing the walls is to arrange the stiffened rings. However, existing regulatory documents offer methods for the arrangement of rings without taking into account the peculiarities of the operation of tanks without a stationary roof and the uneven wind pressure. Using the SolidWorks software, an updated wind load diagram was obtained, which showed differences between it and the normative up to 40% zone of the upper belt. Further, in the LIRA-SAPR, by sequentially enumerating the options, dependencies are determined that allow placing stiffened rings. The expression is determined for tanks with a volume of 10–30 thousand m³, through the λ parameter, taking into account the geometry of the tank and the specified shape of the wind pressure. As a result of the recommendations, the stability of the wall increases in the range of 6–14% compared to the normative placement of the corresponding number of rings.
