The paper presents a mathematical model of deformation of thin-walled cylindrical shell panels, taking into account transverse shears, geometric nonlinearity, and the presence of ribbed stiffeners. Dimensionless parameters are used. The computational algorithm is based on using the Ritz method and the method of continuation of the solution with respect to the best parameter. There are shown the values of critical buckling loads for several variants of structures, depending on the chosen method of taking into account the reinforcement and the number of stiffeners.
