Abstract

A method for the investigation of the dynamic buckling of liquid-filled shells under horizontal excitation has been developed. Strikingly good agreement has been obtained in comparison to available experimental results. This provides guidelines for a better understanding of stability phenomenon of liquid-filled shells. The importance of modal interaction in the axial as well as circumferential directions is also demonstrated. In particular, the coupling between the nth and (n + 1)th circumferential modes is found to be the major cause for the instability of fluid-structure systems under horizontally applied ground motion. For failure conditions in which the buckling modes are not exactly known from the shaking table experiment, the significant bifurcation solutions can be identified from the present analysis.
