The paper considers the problem of stability of a thin-walled channel. Options for increasing the stability of the channel by changing its cross-section are proposed. Stiffness increased by adding triangular folds, as well as by adding stiffeners. The influence of initial imperfections of geometry in the channel model on the critical load of stability loss and postcritical behavior of the model is investigated. Imperfections were defined as deviations of the geometry of the pseudo-random amplitude.
