Abstract: The problem of cross bending the Kirkhoff layers plates of the variable thickness reinforced by filaments of a constant cross-section and working in conditions of steady creep of all phases of a composition is formulated. The system of the resolving equations and boundary conditions corresponding it is analysed. The method of a solution of a task in view is developed. The concrete calculations which have shown are lead, that the velocity of a sag of the steady creep of plates essentially depends on a mode of their fastening, structure of reinforcing and a diversity of distant layers, distribution of thickness of a design and its layers. The path of the approximated solution of such problems in conditions of the unsteady creep is specified.

Keywords: steady creep, layered plates, cross-bending, complex reinforcement.
