It sets a general formulation generalizing Tong's one by a logical step in a lagrangian point of view. A specialized solution algorithm is presented. As launchers are axisymmetric structures, a general theory of axisymmetric structures with cosinusoidal modes is presented, including shells, volumes, and incompressible structures. The problem of setting the ccorrest limiting conditions on the axis is treated. Special pressure terms are also treated. ULiège - Université de Liège LTAS, Université de Liège
