The constructive forms of the lattice surfaces are analyzed and the rational system of the cylindrical shell is chosen. The grid with cells having longitudinal, transverse and diagonal rods was studied. The use of nodes with a rigid connection of elements was taken into account. The features of the stability loss of cylindrical mesh shells within the given geometric parameters are determined. The regularities of systems behaviour under the action of operational loads are founded. It is revealed that with the increase of span and other sizes the coefficient of stability margin of the structure decreases. The forms of the possible onset of the critical state of the shells with increasing imposed load were obtained.
