There can be some imperfections in actual shell structures. In order to achievehighuality in manufacturing structures, the imperfections should be restricted within reonable tolerance ranges through design or examinations. In this paper, the governingquations to solve the dynamic buckling problems of shell structures, which consider namic fluid-structure interaction, model coupling in both axial and circumferential rections, and circumferential imperfections,are derived by using Variationl PrinciplApplying finite element method (FEM) to these equations, the matrix equation of motiois formulated to apply to computer analyses. Therough the implementation of some exames, the influence of the amplitude and pattern of imperfections on the buckling streth is descussed. Also, the validity and applicability of this method to the design ofhell structures is discussed.
