Based on potential flow theory for incompressible, inviscid fluid flow in conjunction with the response spectrum approach, the maximum pressure distribution in the deformable liquid filled cylindrical tank is calculated. The coupled fluid-structure-interaction problem is solved in a semi-analytical manner. By appyling this maximum pressure distribution to the shell incrementally the loss of stability (mainly caused by axial compressive membran forces near the base) is considered by a non-linear finite element analysis. Particularly the influence of shape imperfections on the stability is investigated in the non-linear numerical calculation.
